Boot-Up 11.25.13 / 6 min. 1)Are the s shown ? Yes No 2) Theorem used : ______ 3) Show proof.

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.)
11
6-2a If you prove similarity by virtue of congruence, how many sides do you have to prove are congruent to prove s are ?
12
If 2 sides & the included of one are to the corresponding parts of another , the s are . 1) SAS (Side-Angle-Side) 6-12
13
If 3 sides of 1 are to 3 sides of another , the s are . 2) SSS (Side-Side-Side)
14
If 2 s and the included side of 1 are to the corresponding parts of another , the s are . 3) ASA (Angle-Side-Angle)
15
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)
16
If the hypotenuse & leg of one right are to the corresponding parts of another right , the right s are . HL (Right s Only) 5)
17
Why not AA for Congruence?

8-49a Wanna hint? Read p.506!
24
8-49b This’s tougher than battling Doc Ock! Better re-Read p.506!
25
8-51 Wouldn’t it be great if we could conjure up a shortcut for this?!

Test Rules: 1)No noise / talking / disruptions. 2)Eyes on your own papers. 3)When finished, put pencil down, open textbook, & solve the following problems on pages 517 -- 519: 8-116, 8-119, 8-121, 8-124
