Congruent Triangles
Triangles are congruent if they have the same size and shape. Their corresponding
parts, the angles and sides that are in the same positions, are congruent.
Corresponding Parts
Congruent Angles
A  J
B  K
C  L
Congruent Sides
AB  JK
BC  KL
CA  LJ
To identify corresponding parts of congruent triangles, look at the order of the vertices
in the congruence statement such as ABC  JKL.
Given: XYZ  NPQ. Identify the congruent corresponding parts.
