  1. The Unit Circle Part I MSpencer

  2. r = 1 r = 1 r = 1 r = 1 The Unit Circle It is called a unit circle because the radius is one unit.

  3. r = 1 All the Way Around One way to measure angles is with degrees. One revolution around the unit circle constitutes 360°. Another way of measuring angles is with radians. Since a revolution is the circumference of a circle and r = 1, C = 2r = 2(1) = 2  2 radians is equivalent to 360°
