1. Trig Functions Extended the Circular Functions
Objective: Students will recall the concepts of the unit circle and show that different sized circles yield the same angle measure.

2. Terms
Initial side – where you start to measure angle Vertex – endpoint of ray Terminal Side – ending side of angle Positive Angle – counterclockwise direction Negative angle – clockwise direction of angle Conterminal Angle – same initial side and same terminal side
