In the given figure we have two triangles ΔABC and ΔPQR
Given:


SSS postulate of congruence says that if three sides of a triangle are congruent or equal to corresponding three sides of other triangle then the triangles must be congruent.
Therefore, we need
to show that ΔABC and ΔPQR are congruent by SSS postulate of congruence.
