In the figure, two congruent circles intersect in A and B. If `angle AO'B=50^@` then find `angle APB`

Two congruent circles with centres C and O' intersect at A and B. If angleAO'B = 50^@ , then find angleACB

Two congruent intersecting circles.

In Figure,two congruent circles with centres O and O' intersect at A and B .If /_AO'B=50^(@), then find /_APB

In the figure , if AB = CD and angle AOB =90^@ find angle COD

In the given figure, If angle AOB = 125^(@) then find angle COD .

In the following figure, O is the centre of the circle , AC is the diameter and if angle APB =120^@ , then find angle BQC .

In the figure , if AB = CD and angle AOB = 90^@ find angle COD
