Question

if tow side of triangle are congurent then angle opposite to them is congurent. prove the theroem​

Answer 1

Yes, the angles opposite those sides are always congruent.

Two angles and a non-included side are congruent

∠A≅∠X∠A≅∠X(angle)

∠C≅∠Z∠C≅∠Z(angle)

AB ≅≅ XY (side)

Therefore, by the Angle Angle Side (AAS), the triangles are congruent.
