Angles are the building blocks of trigonometry, and measuring them is key. We'll look at degrees and radians, two ways to describe angles, and how to switch between them. We'll also see how angles relate to circular motion and arc length.
Understanding angles helps us tackle real-world problems. We'll explore how to find related angles, calculate speeds in circular motion, and apply these concepts to things like rotating machinery and planetary orbits. It's all about connecting math to the world around us.
