8.3+TRIANGLE+SIMILARITY.+T&A

OBJECTIVES: 1. Develop th AA Triangle Similarity Postulate and the SSS and SAS Triangle Similarity Theorems.


 * DEFINITIONS AND BLUE BOXES:**

to two angles of another triangle, then the triangles are similar. propotional to the three sides of another triangle, then the triangles are similar. proportional to two sides of another triangle and their included angles are congruent, then ther triangles are similar.
 * AA (ANGLE-ANGLE) SIMILARITY POSTULATE-** If two angles of one triangle are congruent
 * SSS (SIDE-SIDE-SIDE) SIMILARITY THEOREM -** If three sides of one triangle are
 * SAS (SIDE-ANGLE-SIDE) SIMILARITY THEEORM -** If two sides of one triangle are

If you have to determine whether the theorem used is side, side, side (sss) or side, angle, side (sas) or angle, angle (aa) first you have to know how many angles and how many side there are. If there are no angles and just sides that would be the sss. If there are two angles and no sides then it would be aa. If there are more sides then angles and angles are in the problem then it would be called sas.
