APPLYING SIMILARTY USING THE ANGLEANGLE (AA) CRITERIONS ~ADAPTED FROM WALCH EDUCATION ANGLE-ANGLE (AA) SIMILARITY STATEMENT • If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. • it is not necessary to show that the third pair of angles is congruent because the sum of the angles must equal 180˚. PRACTICE #1 • Explain why of , and then find the length • Hint: Similar triangles have corresponding sides that are proportional. SOLUTION • Show that the triangles are similar. • Since and by AA Similarity Statement • Find the length of AB DE 3.4 = = AC DF 6.9 2.72 x (2.72)(6.9) = (3.4)(x) x = 5.52 , then THANKS FOR WATCHING! ~DR.
