F.5 maths circle

1.In the figure, two equal circles intersect at two points P and Q. ACMBD is a straight line and M is the mid point of PQ. PQ is perpendicular to AD, AB=CD=26cm and
PQ=10cm. Show that CM=BM
(Found: radii of the circles=13cm, the distance between the centres of the two
circles =24cm.)
