- SAS congruence rule
If two sides of a triangle and the angle included between them are equal to the corresponding two sides and included angle of another triangle, then the triangles are congruent by SAS congruence rule.
Are ΔABC and ΔRPQ congruent?
In ΔABC and ΔRPQ,
AB = RP
∠ABC = ∠RPQ
BC = PQ
∴ ΔABC ΔRPQ (By SAS congruence rule)
