WebbThe "Unit Circle" is a circle of radius 1, centered at the Origin. We establish the positive x-axis as the "initial side" of an angle, with any ray from the Origin forming its "terminal side". If we draw a segment from the Origin to the point where the terminal side intersects the Circle, we can define that as the Hypotenuse of a right triangle.
