WebThe sides of a 45°, 45°, 90° triangle, which can also be described as a π 4, π 4, π 2 triangle, have lengths in the relation s, s, 2 s. These relations are shown in Figure 8. Figure 8 Side lengths of special triangles. We can then use the ratios of the side lengths to evaluate trigonometric functions of special angles. WebIn previous examples, we evaluated the sine and cosine in triangles where we knew all three sides. But the real power of right-triangle trigonometry emerges when we look at triangles in which we know an angle but do not know all the sides.
