Right angle triangle in a circle

WebThe Reference Angle is the "theta" of the right triangle. Coterminal Angles: Since we can continue around the circle as many times as we like, the angle can exceed 360 degrees ( radians). However, it is easiest to work with angles in the range of 0 - 360 (or 0 - radians). WebAngle formed by a point on a circle and the 2 ends of a diameter is a right angle. For the theorem sometimes called Thales' theorem and pertaining to similar triangles, see …
