What will I do to show that I have learned it?I can...Prove two figures are congruent by congruent marks, given statements, and using SSS, SAS, ASA, AAS, or HL

To prove two triangles are congruent, we use a 2column proof. 1. BUILD after each GIVEN separately. 2. MARK the diagram (if it is not already) as you move through the proof
3. Remember, you are looking for 3 pieces of information to be able to prove the two triangles are congruent!
