Question

In the figure arc AB is congruent to arc CD. If measure angle AOB is 62 degree then find measure angle COD.

Answer 1

Answer:

Arc ab congruent to Arc cd

so Ratios of Aob = Cod

therefore AO:BO= CO:DO

so , AOB = COD = 62°

Answer 2

Answer:

since arc AB is congruent to arc CD therefore the angle subtended by the congruent arcs at the centre will also be equal

therefore,

angle AOB=angle COD= 62°
