Boot-Up / 6 min. 1)Are the s shown ? Yes No 2) Theorem used : ______ 3) Show proof.
6-2b BD = AC BC = BC B C SAS ABD BCA
There are 2 things you have to do to prove congruence. They are: 1) Prove Similarity. (That they’re the Same Shape.) 2) Prove Side Lengths have a common ratio of 1. (That they’re the Same Size.)
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 4) AAS (Angle-Angle-Side)
If the hypotenuse & leg of one right are to the corresponding parts of another right , the right s are . HL (Right s Only) 5)
Why not AA for Congruence?
6-1 Are these s also ? Explain how you know.

8-49a Wanna hint? Read p.506!
8-49b This’s tougher than battling Doc Ock! Better re-Read p.506!
8-51 Wouldn’t it be great if we could conjure up a shortcut for this?!
