Known for his wild performance style, good looks, and musicianship (largely influenced by African-American rhythm and blues), Elvis took the world by storm.
Right Triangle Similarity Acute Angle Similarity If one of the acute angles of a right triangle is congruent to an acute angle of another right triangle, then by Angle-Angle Similarity the triangles are similar. In the figure, â  M â â  Y , since both are right angles, and â  N â â  Z .
Students will calculate the sine and cosine of both acute angles in a right triangle and explain why the sine of one acute angle is equal to the cosine of the complementary angle.irst to be completed will be a table with sides, side lengths, and sine and cosine values for the acute angles of five different triangles. Then, students will identify which values are the same and explain why the sine and cosine values of complementary angles are the same.
