Name the two-dimensional shape
Key Notes:
📌 What is a Two-Dimensional (2D) Shape?
- A 2D shape is flat (has no thickness).
- It has only length and width.
- It can be drawn on paper.
🔷 Common 2D Shapes
🔵 Circle

- Round shape
- No corners or sides
- Example: ball, clock
🟨 Square

- 4 equal sides
- 4 corners
- Example: window, tile
🔺 Triangle
- 3 sides
- 3 corners
- Example: pizza slice, signboard
▭ Rectangle

- 4 sides
- Opposite sides are equal
- Example: book, door
✏️ How to Identify Shapes
- Count the sides
- Count the corners (vertices)
- Look at the shape carefully
🎯 Simple Tips for Students
- Circle = round
- Triangle = 3 sides
- Square = all sides equal
- Rectangle = long and short sides
🧠 Practice Ideas
- Ask students to name shapes in the classroom
- Draw shapes and let them identify and color
- Match shapes with real-life objects
Learn with an example
What shape is this?

- Circle
- Triangle
- Square
Look at the sides and vertices to name the shape.
Sides are the straight lines that make the shape. Count the sides all around the shape.

Vertices are where two sides of the shape meet. Count the vertices.

A shape with 3 sides and 3 vertices is a triangle.

Look at the sides and vertices to name the shape.
Sides are the straight lines that make the shape. Count the sides all around the shape.

Look closely at the 4 sides on the shape. They are all equal.

Vertices are where two sides of the shape meet. Count the vertices.

Look closely at the 4 angles on the shape. They are all right angles.

A shape with 4 equal sides and 4 right angles is a square.

- Triangle
- Square
The shape is completely round.

The shape has no vertices. It is a circle.
