well looks like circle geometry call the let X be the intersection of BD and AC in Tri DBC and tri CBA angle BAC = angle BDC angles standing on the same are are equal. Angle BXA = angle CXD vertically opposite angles. AB = CD equal angles subtend equal chords. therefore tri DBC is congruent to tri CBA (Angle Angle Side test) hence BD = AC corresponding sides in congruent triangles.

there are 4 tests for congruent triangles, 1. Side, Side Side 2. Side Angle Side 3 Angle Angle Side 4 Right Hypotenuse Side.. if the 2 triangles are congruent... all corresponding sides and angles are equal
