Similar Triangles

Similar triangles have the same shape, but not necessarily the same size. Two main tests for similarity: 1)If the angles of 1 triangle and the corresponding angles of a 2 triangle have equal measures, then the triangles are similar 2)If the measures of the sides of 2 triangles form equal ratios, or are proportional, then the triangles are similar

Similar Triangles If 2 triangles are similar, then the measures of their corresponding sides are proportional, and the measures of their corresponding angles are equal.
