6-2a
If you prove similarity by virtue of congruence, how many sides do you have to prove are congruent to prove s are ?
If 2 sides & the included of one are to the corresponding parts of another , the s are .
1) SAS (Side-Angle-Side)
6-12
If 3 sides of 1 are to 3 sides of another , the s are .
2) SSS (Side-Side-Side)
If 2 s and the included side of 1 are to the corresponding parts of another , the s are .
3) ASA (Angle-Side-Angle)
If 2 s and the non-included side of one are to the corresponding parts of another , the s are .
AAS
