This document discusses identifying congruent figures and their corresponding congruent parts. It defines congruent figures as having the same shape and size, with their corresponding parts (matching sides and angles) being congruent. It provides two examples of naming congruent sides and angles of congruent triangles based on either a visual comparison or a stated congruence. The document checks the reader's understanding with two short problems identifying congruent parts of triangles.
