How can trigonometry be used to find the area of a triangle or parallelogram? Does the triangle need to be a right triangle, and how accurate can the results possibly be? The answers to these questions are found here along with several explained examples so students can see the formula in action. A link to practice problems (including some real-world applications) is also provided.
