Problem 453: Intersecting Circles, Tangent, Circular
Segment, Congruence, Area

The figure shows the intersecting circles O
and O' at A and B. Line CO is tangent to circle O' at O, lines CDA and
CO' are chords of circle O. Prove that the circular segments S and S'
are congruent.
A circular segment is an area of a
circle enclosed between a chord and the arc whose endpoints equal the
chord's.
