2D Shapes
A 2D (two-dimensional) shape is flat with only two dimensions.
For example, the Football field is rectangular.
Properties of 2d shapes
Properties mean the features of different shapes. It includes:
→ number of sides
→ length of sides
→ number of vertices
→ types of angles
→ parallel or perpendicular lines
Let us discuss the properties of different 2d shapes.
Circle
A circle is a flat round 2d shape.
It is made up of one curved line.
Triangle
A triangle is a 2d shape with three sides.
Quadrilateral
