1. 4-5 Proving Triangles Congruent (ASA , AAS) Ms. Andrejko

2. Vocabulary • Included side- the side located between two consecutive interior angles of a polygon

3. Real-World

4. Postulates/Theorems/Corollaries • P 4.3: If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent • T 4.5: If two angles and the non-included side of one triangle are congruent to the corresponding two angles and side of a second triangle, then the two triangles are congruent

11. Trying Something New (6th Period) • Stand against the side wall • Choose your seat where YOU WOULD LIKE IT • Suggestions: • If you would like to learn, pick a seat FRONT & CENTER • If you don’t care about the material, pick a seat as far in the back as possible, so you aren’t distracting the rest of us.
