This is a bundle of lesson slides, 2 worksheets, and a quiz for an honors-caliber Geometry class. It serves as an added section to Unit 4 - triangles, and uses Sine & Cosine in order to rotate figures about the origin, at any angle (for example, in a coordinate plane, rotate the figure 78° clockwise about the origin). The lessons serve as a great way to introduce Sine and Cosine early on to the class, as well as explore a topic not widely discussed in a typical Geometry curriculum. The bundle
