This unit teaches students how to apply trigonometry concepts like trig identities, inverses, and right triangle trigonometry to solve real-world measurement problems. Students will learn to measure objects in nature, man-made structures, and historical objects. They will also use trig functions to model real-life situations and create a project using trigonometry to measure a real object, which they will present to the class. The goal is for students to understand how trigonometry applies to measuring the physical world.
