Circle Shape
A circle is a round shape with no corners and no sides. It is one of the first shapes children learn in Class 1. Circles are everywhere — from the wheels of a bicycle to the face of a clock.
A circle looks the same from every direction. No matter how you turn it, it stays round. This makes the circle a very special shape.
What is Circle Shape - Class 1 Maths (Shapes and Space)?
A circle is a flat, round shape where every point on its edge is the same distance from the centre. It has no sides, no corners, and no straight edges.
Important parts of a circle:
- Centre: The middle point of the circle
- Edge (boundary): The round line that forms the circle
Types and Properties
Big and Small Circles
Circles can be any size. A bangle is a small circle. A hula hoop is a big circle. But all circles are round.
