Possible answer: The sine ratio of an acute angle is determined by the measure of the angle. Because the sine ratios of the acute angles are equal, the angles are congruent. The right angles of the triangles are also congruent. Therefore, the triangles
WebJun 11, 2024 · Since the ratios for sin α and cos β are the same, sin α = cos β, and the ratios for cos α and sin β are the same; additionally, ... A square has side lengths of 7√2.
