First I explain the difference between a line and a ray in geometry. Then, an angle is defined as two rays originating from the same point - called the vertex of the angle.
I discuss the size of an angle, and how it does not depend on the sides of an angle. I show the imaginary arc of a circle that is drawn when an angle opens further and further. Lastly I go through a few exercises about which angle is bigger.
