The distance from the centre to any point on the circle. All radii of a circle are equal.
A line segment passing through the centre and touching both ends of the circle. It is twice the radius.
\( \text{Diameter} = 2 \times \text{Radius} \).
A chord is any line segment joining two points on a circle.
The diameter is the longest chord.
A part of the circumference between two points is called an arc.
The smaller arc between two points on a circle.
The larger arc between the same two points on a circle.
A \(180^\circ\) arc formed by endpoints of the diameter.
A region bounded by a chord and its corresponding arc.
Minor segment and major segment.
A region enclosed by two radii and the connecting arc.
The angle subtended at the centre by an arc or chord.
