Question

What else would need to be congruent to show that ABC DEF by SAS?

Answer 1

A) Angle A has to be congruent to Angle D

Answer 2

Option A. <A≅<D.

Explanation:

Two triangles are congruent by SAS congruence property if two sides and the angle between the two equal sides is congruent in both the triangles.

It is given the sides AB ≅ DE and AC≅DF in triangles ABC and DEF.

The angles between these equal sides are <A and <D .The triangles will be congruent by SAS if <BAC ≅<EDF.

Option A. <A≅<D. is the correct ption.
