#### Trigonometry Unit Assessment

*75 min*

This Trigonometry Unit Assessment features foundation, application, and extension problems so that students can demonstrate different levels of mastery of trigonometry ideas. In the foundations section, for example, students use trigonometric ratios to solve basic problems (#1, 2, 6). In the application and extension part of the assessment, students have the opportunity to apply what they know about trigonometry in complicated or novel problems or problems that require them to synthesize several geometry ideas from throughout the school year (#8, 11).

I want to give students an opportunity to push their thinking even more, which is why I include an extra credit opportunity, where students can prove the Law of Sines.
