# From the figure, identify:

(a) the centre of a circle

(b) three radii

(c) a diameter

(d) a chord

(e) two points in the interior

(f) a point in the exterior

(g) a sector

(h) a segment

**Solution:**

A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (centre) in the plane.

(a) The centre of the circle is O.

(b) The three radii of the circle are OC, OA and OB.

(c) The diameter of the circle is AC.

(d) The chord of the circle is ED.

(e) Two points in the interior of the circle are O and P.

(f) A point in the exterior of the circle is Q.

(g) A sector in the circle is sector OBC.

(h) A segment in the circle is ESDE.
