Using the trigonometric ratios shown in the preceding equation, the following trigonometric identities can. Following is the trigonometric ratios table which contains all the trigonometric ratios of standard angles: The trigonometric ratios for the angles 30°, 45° and 60° can be found using two special triangles.

Consider the general right angle triangle, in figure 1 below, with angle β and sides labeled as , , this property makes them have special names.

This lesson will summarize the trigonometric ratios of special angles taken from lesson #1 to lesson #6. The values of the angle are important for solving various trignometry problems. Following is the trigonometric ratios table which contains all the trigonometric ratios of standard angles: A right angled triangle is a triangle where one of the internal angles is 90°.
