Question

In the given figure O is the centre of circle of radius 5cm. OP perpendicular CD,AB parallel to CD
AB = 6 cm and CD= 8cm. Determine PQ 5 points

Answer 1

Answer:

Join OA and OC. Since, the perpendicular from the centre of the circle to a chord bisects the chord. Therefore, P and Q are mid- points of AB and CD respectively. ∴ PQ = OP + OQ = (4 + 3) cm = 7 cm
