Question

You want to establish $△DEF\cong △MNP$, using ASA congruence rule. You are given that $\angle D=\angle M$ and $\angle F=\angle P$. What information is needed to establish the congruence ?

Answer 1

Given:- $\angle D=\angle M\angle F=\angle P△DEF\cong △MNP\left(\text{By ASA congruent rule}\right)$

As we know that if angle on either side are equal then the sides are also equal.

Thus the $DF=MP$ is the needed information to establish the congruence.
