In Fig. 2.47, O is the centre of the circle.
(a) Name all chords of the circle.
(b) Name all radii of the circle.
(c) Name a chord, which is not the diameter of the circle.
(d) Shade sectors OAC and OPB.
(e) Shade the smaller segment of the circle formed by CP.
(a) Chords: PC and AB (longest chord i.e. diameter).
(b) Radii: OA, OB, OC and OP (radii are those whose one end point lies on the circumference of the circle and other end coincides with the centre of the circle.
Region shaded in green colour represents sector (OPB) and region shaded in red colour represents sector (OAC).
Region shaded in green represents the smaller segment of the circle formed by CP.
