Question

State and prove 1. SAS congruence​

Answer 1

If any two sides and the angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.

Hence, Δ ABC ≅ Δ PQR.
