On the other side of this worksheet, we used the Pythagorean Theorem to find a missing side of a right triangle when given the other two sides. Now we will use trigonometry to find a missing side or angle when given a side and an angle or when given two sides of a right triangle. We will need to develop three trigonometric ratios: sine, cosine ...
