What are bearings in math? | IB SL Math AA and AI

Have you been confused about how to do bearings in your math class? Why do we use bearings in math classes? We'll answer these questions in this video.
Bearings can be confusing because it requires an understanding of not only directions, but parallel lines and transversals, properties of triangles, the Sine Rule, and the Cosine Rule. All of these topics work together to problem solve the question "What is the bearing of one point from another point?". It can be confusing sorting through all that you need to know when solving bearings in your math class. But stick with me and I'll get you sorted out.
