### Intro to G.6

Congruent Triangles

Congruent figures are two figures that have the same size and shape.

IF two figures are congruent THEN they have the same size and shape.

IF two figures have the same size and shape THEN they are congruent.

Two figures have the same size and shape IFF they are congruent.

Congruent Triangles - CPCTC

Corresponding Parts of Congruent Triangles are Congruent

CPCTC:

Two triangles are congruent IFF their corresponding parts (angles and sides) are congruent.

=

Vertices of the 2 triangles correspond in the same order as the trianglesare named.
