3
Congruent triangles have 3 congruent sides and 3 congruent angles. The parts of congruent triangles that “match” are called corresponding parts.

4
In a congruence statement ORDER MATTERS!!!! Everything matches up.

14
There are 5 ways to prove triangles congruent.

15
Side-Side-Side (SSS) Congruence Postulate All Three sides in one triangle are congruent to all three sides in the other triangle

16
Side-Angle-Side (SAS) Congruence Postulate Two sides and the INCLUDED angle (the angle is in between the 2 marked sides)

17
Angle-Angle-Side (AAS) Congruence Postulate Two Angles and One Side that is NOT included

18
Angle-Side-Angle (ASA) Congruence Postulate Two angles and the INCLUDED side (the side is in between the 2 marked angles)

19
There is one more way to prove triangles congruent, but it’s only for RIGHT TRIANGLES…Hypotenuse Leg

20
Your Only Ways To Prove Triangles Are Congruent NO BAD WORDS

21
2 markings you can add if they aren’t marked already

22
Share a side Reason: reflexive property Vertical Angles Reason: Vertical Angles are congruent
