Understanding Triangle Congruence
SSS Congruence
If all three sides of one triangle are equal to the corresponding sides of another, the triangles are congruent.
ASA Congruence
Two angles and the included side of one triangle must match the other for congruence.

Problem 1
Given ΔABC ≌ ΔPQR by SAS criterion, where AB=4cm, BC=6cm, and angle B=60°, what are the measures of PQ and QR?
Problem 2
Are these triangles congruent? If yes, state the criterion. (Include SVG of two triangles in your actual build).
