GEOM 3 | Lesson 1 | Watch (Congruence)

With rigid transformations we saw that the figure did not change size or shape.  We can say then that the figures are congruent.   We are going to use that fact to examine how we might prove that triangles are congruent.

Watch the following video on triangle congruence theorems:

Summarize and define all 5 theorems from the video.

1)  SSS.

2)  SAS.

3)  ASA.

4) AAS.

5) HL.

Are ASA and AAS are the same theorem? Discuss and justify why they are actually different using your work as an example.
