Trigonometric Ratios: Sine
Right triangles have ratios to represent the angles formed by the hypotenuse and its legs. Sine ratios, along with cosine andtangent ratios, are ratios of the lengths of two sides of the triangle. Sine ratios in particular are the ratios of the length of the side opposite the angle they represent over the hypotenuse. Sine ratios are useful in trigonometry when dealing with triangles and circles.
