In the given figure, if OA = 5 cm, AB = 8 cm and OD is perpendicular to AB, then CD is equal to:
A. 2 cm
B. 3 cm
C. 4 cm
D. 5 cm
Answer:A
In the given figure, if OA = 5 cm, AB = 8 cm and OD is perpendicular to AB, then CD is equal to:
A. 2 cm B. 3 cm C. 4 cm D. 5 cm
Explanation: From the given diagram, we can observe that OC is perpendicular to chord AB. Therefore, OC bisects the chord AB Hence. AC=CB
