6-3 Similar Triangles
 Angle-Angle (AA) Similarity- If two angles of one triangle are congruent to two angles
of another triangle, then the triangles are ______________.
 Side-Side-Side (SSS) Similarity- If the measures of the corresponding ___________ of
two triangles are proportional, then the triangles are similar.
 Side-Angle-Side (SAS) Similarity- If the measures of two sides of a triangle are
proportional to the measures of two corresponding sides of another triangle and the
____________________ angles are congruent, then the triangles are similar.
 Examples:
1. If you wanted to measure the height of the Sears tower in Chicago, you could
measure a 12-foot light pole and measure its shadow. If the length of the shadow was 2
feet and the shadow of the Sears Tower was 242 feet, what is the height of the Sears
Tower?
2. Given UT || RS , find SQ and QU.
