Question

ASA postulate help!!!!

Answer 1

ASA (Angle-Side-Angle) Postulate

If two angles and the included side of a triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

In the figure, $\angle B \cong \angle E, \overline{BC} \cong \overline{EF}$ and $\angle C \cong \angle F$ .

Therefore, by the ASA postulate, $\triangle ABC \cong \triangle DEF$ .
