WebThe trigonometric ratios If we fix an acute angle \(\theta\), then all right-angled triangles that have \(\theta\) as one of their angles are similar. So, in all such triangles, corresponding pairs of sides are in the same ratio. The side opposite the right angle is … WebWe first describe trigonometric functions in terms of ratios of two sides of a right angle triangle containing the angle θ. θ. With reference to the above triangle, for an acute angle θ θ (that is, 0 ≤ θ< π/2 0 ≤ θ < π / 2 ), the six trigonometric functions can be described as follows: Definition 1.36.
