Question

In the following figure, check the congruency by SAS congruence condition? If congruent, write the congruence of two triangles in the symbolic form :

Answer 1

Checking the congruency:

In $∆PRQ$ and $∆MLN$,

$PR=ML$ [ Each side $2cm$]

$\angle P=\angle M$ [ Each angle $110°$]

$RQ=LN$ [ Each side $7cm$]

But here $\angle P$ and $\angle M$ are not the included angles of the two corresponding equal sides.

Also,$\angle R$ and $\angle M$ are the included angles but we don;t know whether they are equal or not.

Hence, $∆PRQ$ is not congruent $∆MLN$
