Example 1

Proving Congruence SAS

In triangles ABC and PQR, AB = PQ, BC = QR, and angle B = angle Q. Are they congruent?
ABCPQR

Calculation Steps:

  1. 1Identify matching parts: two sides (AB=PQ, BC=QR) and their included angle (B=Q) are equal.
  2. 2Apply SAS criteria.
  3. 3Triangles are congruent.
SolutionYes, by SAS criteria
