Trigonometric Ratios. For a right angle triangle, the relationship between lengths of sides and angles is described using the trigonometric ratios. . The 3 primary trigonometric ratios are: sine (sin), cosine (cos) and tangent (tan). For a given angle, A, the primary trig ratios are defined as follows: Sin(A) = hypotenuse.
