To prove "The line drawn through the centre of a circle to bisect a chord is perpendicular to the chord", we prove congruence of which two triangles?

The center of the circle lies

The shaded portion of the circle represents

A chord divides a circle into two

In the given figure, $$r$$ represents

In the adjoining figure, in $$\triangle OAM \ and \ \triangle OBM$$,
                        $$ OA = OB $$
                        $$AM = BM $$
                        $$OM = OM $$
$$\triangle OAM \ \cong \ \triangle OBM$$ 
What can you conclude?
