In this lesson our instructor talks about exploring congruent triangles. She talks about corresponding parts and sides of triangles. Then she defines congruent triangles and talks more about triangle congruence. Four extra example videos round up this lesson.
Two triangles are congruent if they have the same size and shape
Corresponding angles and sides of triangles must be named in the same order
Definition of Congruent Triangles: Two triangles are congruent if and only if their corresponding parts are congruent
Congruence of triangles is reflexive, symmetric, and transitive
