A circle can be defined as the locus of points, moving from a fixed point which is the centre of the circle to a fixed distance, which is the circumference.
The circumference is always equidistant from the centre.
Parts of a Circle:
Parts of the circle include:
i. Circumference: This is a curved line around a circle or the outer part of a circle.
ii. Diameter: It is a straight line that passes through the centre of a circle and touches the circumference at both sides.
iii. Radius: It is a straight line drawn from the centre of a circle to touch the circumference.
Radius = \( \frac{diameter}{2} \)
Diameter = Radius × 2
