Writing Trigonometric Ratios. Warm-Up. A trigonometric ratio is a ratio of two sides of a right triangle. We can use trigonometric ratios to relate the angles of a triangle to the lengths of the triangle’s sides. In a right triangle, three relationships exist which relate the angles of a triangle to the measures of its sides. The word . opposite
