Decoding the Geometry: Exploring the Fascinating World of Shape Names


Understanding shape names is fundamental to grasping the principles of geometry. This knowledge is crucial not only for academic purposes but also for real-life applications. By learning the names and properties of shapes, we can better describe and comprehend the world around us. This blog will cover the basics of shape names, the geometric vocabulary associated with them, the classification of shapes, and the importance of geometric knowledge.

What Are Shape Names?

Definition of Shape Names

Shape names refer to the specific terms used to identify various geometric figures. These names help distinguish one shape from another, allowing for precise communication and understanding in mathematical contexts and beyond.

Importance of Naming Shapes for Communication and Understanding

Naming shapes is essential for clear communication in geometry. It allows us to describe objects accurately, share ideas, and solve problems more effectively. Understanding shape names also enhances our ability to learn and apply geometric concepts, making it easier to grasp more complex mathematical theories.

Common Shapes and Their Names

Common shapes include:

  • Triangle: A three-sided polygon
  • Square: A four-sided polygon with equal sides and angles
  • Circle: A round shape with all points equidistant from the center
  • Rectangle: A four-sided polygon with opposite sides equal
  • Pentagon: A five-sided polygon
  • Hexagon: A six-sided polygon
  • Cube: A three-dimensional shape with six square faces

The Language of Geometry

Geometric Vocabulary Related to Shape Names

Geometry has its own language that helps describe shapes and their properties. Key terms include:

  • Vertices: The points where two or more edges meet
  • Edges: The line segments where two faces of a shape meet
  • Faces: The flat surfaces of a three-dimensional shape
  • Angles: The space between two intersecting lines or surfaces

Understanding these terms is crucial for grasping more complex geometric concepts. It allows us to describe shapes accurately, analyze their properties, and solve geometric problems efficiently. This foundational knowledge is essential for further study in mathematics and related fields.

Classifying Shapes

How Shapes Are Classified

Shapes are classified based on their properties, such as the number of sides, angles, and dimensions. This classification helps in organizing and understanding the diverse world of geometric figures. By categorizing shapes, we can better analyze their characteristics and relationships, making it easier to study and apply geometric principles in various fields, from architecture to engineering and beyond.

Different Types of Shapes

There are several primary categories of shapes, each with unique properties and characteristics. The main types include polygons, circles, and solids.


Polygons are flat, two-dimensional shapes with straight sides. They are named based on the number of sides they have. Here are a few common examples:

  • Triangle: A polygon with three sides, three vertices, and three angles. Triangles can be further classified into different types based on their angles (e.g., acute, obtuse, right) and sides (e.g., equilateral, isosceles, scalene).
  • Square: A four-sided polygon where all sides are equal in length, and all angles are right angles (90 degrees). The square is a specific type of rectangle and rhombus.
  • Pentagon: A polygon with five sides and five angles. A regular pentagon has all sides and angles equal, whereas an irregular pentagon does not.


Circles are unique among shapes because they are defined by a single curve. A circle is a round shape with all points equidistant from the center. This distance is known as the radius. Circles are fundamental in geometry due to their symmetry and the properties that arise from their consistent curvature.


Solids are three-dimensional shapes that have depth in addition to length and width. They occupy space and have volume. Common examples of solids include:

  • Cube: A three-dimensional shape with six equal square faces, twelve edges, and eight vertices. Each angle in a cube is a right angle. The cube is a type of rectangular prism.
  • Sphere: A perfectly round three-dimensional shape where every point on the surface is equidistant from the center. This distance is called the radius, and the diameter is twice the radius. Spheres are symmetrical in all directions.
  • Pyramid: A solid shape with a polygonal base and triangular faces that converge to a single point (apex). The most well-known pyramid is the Egyptian pyramid, which has a square base.

 Examples and Explanations of Each Type

To better understand these classifications, let’s look at specific examples:

  • Triangle: Three sides, three vertices, and three angles. Triangles are the simplest polygons and are foundational in the study of geometry.
  • Square: Four equal sides and four right angles. Squares are a type of regular polygon and are notable for their symmetry and simplicity.
  • Pentagon: Five sides and five angles. Regular pentagons have equal sides and angles, making them a common shape in various geometric contexts.
  • Circles: A round shape with a constant distance from the center to any point on the perimeter, known as the radius. Circles are integral to understanding concepts like pi, circumference, and area.
  • Cube: Six equal square faces, with all angles being right angles. Cubes are used in various applications, including dice, boxes, and in understanding three-dimensional space.
  • Sphere: A perfectly round three-dimensional shape. Spheres are found in nature (e.g., planets, bubbles) and are critical in understanding volume and surface area in three dimensions.

By recognizing and classifying shapes based on these properties, we enhance our ability to communicate about and work with geometric figures, paving the way for deeper exploration and application of geometry.

    Cambridge Pathway School

    Cambridge Primary starts learners on an exciting educational journey. Typically for 5 to 11-year-olds, it develops young learners who are confident, responsible, reflective, innovative, and engaged and includes an assessment that proves and improves learning. Students in this programme follow Stages 1 to 6 of the Cambridge Primary Curriculum, which continues to build on the foundations that are established in the Early Years Foundation Stage. Ongoing reviews ensure that each student’s progress and development are continuous and meet predetermined standards.

    We encourage students to think independently, use their initiative, and participate in a meaningful and active manner in the learning process. At the end of Grade 5 (Stage 6), students will prepare for the University of Cambridge Primary Checkpoint Examinations in English, Mathematics, and Science. The tests are marked in Cambridge to provide an international benchmark of learner performance. Learners receive a statement of achievement and a diagnostic feedback report. Feedback reports show how a learner has performed in relation to the curriculum, their learning group, the whole school, and against all learners who have taken tests in that series around the world.

    The core academic curriculum includes instruction in English, Mathematics, Science, Global Perspective (Social Studies & EVM) and Digital Learning. Kannada is taught to all students and caters for native and non-native speakers. In addition, the school offers French and Hindi. The overall educational experience is enhanced and supplemented with an enriched visual and performing arts programme that embraces both western and local culture as well as an excellent school sports provision.

    The Finnish Education Model

    Freedom to choose, express, explore and learn. These are the wings of the learning flight in PNCCS. Our pedagogy adaption to the world’s best education system is to prepare today’s learners for Gen-Z. As a resource school, it is our endeavour in providing an enriching learning environment for our Cognitions to learn.
    The Finnish Adaptation in our school is characterized by the understanding that a student who is happy in the classroom and is comfortable since he/she is free to learn at his own pace, will learn the knowledge that is needed. Finnish teachers have genuine pedagogical freedom, as well as autonomy to teach. Therefore, they are motivated in their day to day activities. Teachers spend approximately 400 + hours of training during a year. This includes a wide range of skills such as Subject Matter Expertise, Classroom Management, Equipping Students with 21st Century Skills, and many more.
    The Facilitators have at their disposal a range of ready-to-use materials in their classrooms. The learning labs and Research Points empower the teacher to promote experiential and active learning.
    Thus a plant rooted in good soil and environment bears fruits that sustains itself and the community. And so is every Cognition.
    Progressing in this pathway, two initiatives that shape our children’s mind is “Speakathon” and “Thoughtcast”. These learning platforms help the learners to reflect on various topics which impact them, the environment, and the community at large. Learners express, debate, and pen down their thoughts. Thus transforming them into confident individuals who can voice their opinions, accept or reflect on critical reviews and collaborate to find solutions.
    The pedagogy promotes mastery of learning through thinking routines. It is a synonym for the layers of soil. Each is different in texture and composition but all are important.
