Start Unit test. Triangles are not always right (although they are never wrong), but when they are it opens up an exciting world of possibilities. Not only are right triangles cool in their own right (pun intended), they are the basis of very important ideas in analytic geometry (the distance between two points in space) and trigonometry.

First, we need to create our right triangle. Figure 7.2.1 7.2. 1 shows a point on a unit circle of radius 1. If we drop a vertical line segment from the point (x, y) ( x, y) to the x -axis, we have a right triangle whose vertical side has length y y and whose horizontal side has length x x. Now that you know both the trig ratios and the inverse trig ratios you can solve a right triangle. To solve a right triangle, you need to find all sides and angles in it. You will usually use sine, cosine, or tangent; inverse sine, inverse cosine, or inverse tangent; or the Pythagorean Theorem. Exercises: 2.2 Right Triangle Trigonometry Exercises Homework 2.2. Skills.

Figure 6.5.9: The sine of π 3 equals the cosine of π 6 and vice versa. This result should not be surprising because, as we see from Figure 6.5.9, the side opposite the angle of π 3 is also the side adjacent to π 6, so sin( π 3) and cos( π 6) are exactly the same ratio of the same two sides, √3s and 2s.
