To apply AA, SAS, and SSS Similarity
Angle-Angle Similarity Postulate
(AA ) Postulate ____________________________________________________________________________
If two angles of one
triangle are congruent to two angles of
another triangle then the two triangles
If two sides of one triangle are proportional to two sides of another triangle, and the included angle in one triangle is congruent to the included angle in the other triangle, then the
two triangles are similar.
If the corresponding sides of two triangles are proportional, then the two triangles are similar.
Theorem 8-2: Side-Side-Side Similarity (SSS ) Theorem______
Indirect measurement is _______________________________________________________________________________________________________________.
measurement of very large objects or of long distances (which are often made indirectly), using similar triangles and proportions
Alex Giulano’s eye is 168 cm above the ground while he is standing 114 cm from the mirror. If the mirror is 570 cm from the flagpole, how tall is the flagpole?
I ♥ Geometry!
1. You want to prove that
by the SSS Theorem. Complete the
proportion that is needed to use this
FH = a = FG
b = XS = c
Name a postulate or theorem that can be used to prove that the two triangles are similar. Then, write a similarity statement.
