Question

In triangles ABC and DEF, AB = FD and ∠A = ∠D. The

Q: Answer-In triangles ABC and DEF, AB = FD and ∠A = ∠D. The two triangles are congruent by SAS criterion if:

Side AB FD one pair of sides are equal Angle A D one pair of angles are equal To satisfy the SAS criterion, we need one more pair of sides that are opposite the given angle. Since the given angle is AD, we must find the side opposite to these angles In ABC, the side opposite to A is AC. In DEF, the side opposite to D is DE. Therefore, AC DE

two triangles are congruent by SAS criterion if:

A BC = DE

B AC = EF

C BC = EF

D AC = DE
