Question

If ΔDEF˜ ΔABC and DE = AB, what is the relation between the two triangles?​

Answer 1

Answer:

Given, in ΔABC and ΔDEF, AB = DF and ∠A = ∠D

We know that, two triangles will be congruent by ASA rule, if two angles and the included side of one triangle are equal to the two angles and the included side of other triangle.

∴ AC = DE

Answer 2

Answer:

both triangles are congruent
