... always be of length 1. Now consider any right triangle. You can imagine this angle being at the origin, but the sine and cosine will not give you the coordinate of the other two vertices. However, because the triangle is similar with the triangle with hypotenuse 1 of the same angle, the ratio betwee ...

... truth established by means of accepted truths. 1. Vertically opposite angles are equal in measure. 2. In an isosceles triangle the angles opposite the equal sides are equal. Conversely, if two angles are equal, then the triangle is isosceles. 3. If a transversal makes equal alternate angles on two l ...
