In this resource, students will practice the Law of Sines and Law of Cosines (also known as the Sine Rule and Cosine Rule.) This worksheet includes a summarizing graphic organizer (which can be completed together as a class) and then additional practice problems (which students can complete independently.) In the practice problems, students must draw a triangle that represents the given information, identify which rule to use, and then solve for the missing value.

Answer key included for easy classroom implementation!
