SIMILAR POLYGONS Corresponding angles which are the same measure and corresponding sides which are proportional in length.
SIMILAR POLYGONS Which two rectangles are similar?
SIDE – SIDE – SIDE TRIANGLE SIMILARITY If two triangles have proportional corresponding side lengths, then the triangles are similar
ANGLE – ANGLE – ANGLE SIMILARITY If the angles of one triangle are congruent to the angles of another triangle, then the triangles are similar and their corresponding side lengths are proportional. 35 ⁰ 40 ⁰ 105 ⁰ 35 ⁰ 40 ⁰ 105 ⁰
