Answer these questions with your partner once you are finished.

1) What is the minimum amount of information necessary to conclude triangles are congruent?

2) How do we know figures are congruent?

3) Based on the activity, can you come up with new postulates that prove triangles congruent?

Triangle Congruence

• 3 pieces of information is necessary• Order matters

Side-Side-Side (SSS) Postulate

If the three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent

Side-Angle-Side (SAS) Postulate

If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent

Two Colum Proof

Given: M is the midpoint of segment XY, ax is congruent to AY

Prove: AMX is congruent AMYA
