Congruent triangles have 3 congruent sides and 3 congruent angles. The parts of congruent triangles that “match” are called corresponding parts.
In a congruence statement ORDER MATTERS!!!! Everything matches up.
Corresponding Parts of Congruent Triangles are Congruent

There are 5 ways to prove triangles congruent.
Side-Side-Side (SSS) Congruence Postulate All Three sides in one triangle are congruent to all three sides in the other triangle
Side-Angle-Side (SAS) Congruence Postulate Two sides and the INCLUDED angle (the angle is in between the 2 marked sides)
Angle-Angle-Side (AAS) Congruence Postulate Two Angles and One Side that is NOT included
Angle-Side-Angle (ASA) Congruence Postulate Two angles and the INCLUDED side (the side is in between the 2 marked angles)
There is one more way to prove triangles congruent, but it’s only for RIGHT TRIANGLES…Hypotenuse Leg
