Name the two-dimensional shape

Key notes :-

1. Definition of Two-Dimensional Shapes:

  • A two-dimensional shape has only two dimensions: length and width.
  • These shapes do not have thickness and can be drawn on flat surfaces like paper.

2. Examples of Two-Dimensional Shapes:

  • Circle: A round shape with no corners or sides.
  • Square: A shape with four equal sides and four right angles.
  • Rectangle: A shape with four sides, opposite sides are equal, and four right angles.
  • Triangle: A shape with three sides and three corners.
  • Oval: A shape that looks like a stretched circle.

3. Properties of Two-Dimensional Shapes:

  • Circle: 1 curved side, no corners.
  • Square: 4 equal sides, 4 corners.
  • Rectangle: 4 sides, opposite sides are equal, 4 corners.
  • Triangle: 3 sides, 3 corners.
  • Oval: 1 curved side, no corners.

4. Recognizing Two-Dimensional Shapes:

  • Look for shapes that are flat and can be seen from one side.
  • Shapes can be found everywhere in daily life: road signs (triangle), windows (rectangle), coins (circle), etc.

✈️What shape is this?

  • circle
  • triangle
  • square
  • The shape is completely round.
  • The shape has no vertices. It is a circle.

✈️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.

_________________________________________________

  • 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.
