Congruent Triangles Section 4.2

Definition of Congruent Figures Two geometric figures are congruent if they have exactly the same size and shape. In two congruent figures, each part of one figure has a matching, congruent part in the other figure. The matching pieces are called corresponding parts.

Congruence Statements The congruence statements MUST be written in the correct order.

Write a Congruence Statement

Third Angles Theorem If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent.
