1. Triangle Congruence Shortcuts Review
Objective:
To prove two triangles congruent using the shortcuts

2. Angles
Included vs. Excluded

3. Three Parts? Side-Angle-Side (SAS) Side-Side-Side (SSS)
Angle-Side-Angle (ASA)
Side-Angle-Angle (SAA)
Side-Side-Angle (SSA)
Angle-Angle-Angle (AAA)

4. Side-Side-Angle (SSA)B
∆BAD
∆BAT T D A

5. Angle-Angle-Angle (AAA)
Is this statement true?
∆MNO
∆PQR

6. Yes! Which two triangles are congruent by ASA? Explain.
To use ASA, we need two pairs of congruent angles and a pair of included congruent sides.
Do congruent sides have congruence markings (ticks)?
Yes!
