Objective: Convert between degrees and radians. Draw angles in standard form. Warm up Fill in the blanks. An angle is formed by two_____________ that have a common point called the ______________ of the angle.

Positive Angle: Rotate initial side counter clockwise. Negative Angle: Rotate initial side clockwise.

Radian Measure: The measure of (theta) in radians of a central angle is equal to the ration of the length of the intercepted arc (s) to the radius of the circle.

Example 1 A central angle in a circle of radius 12 ft intercepts an arc of length 42 ft. What is the radian measure of. Degrees and Radians

Convert: Degrees to radians. Multiply by Radians to degrees. Multiply by Example 2 Convert each angle in degrees to radians. a. b. c.

Example 3 Convert each angle in radians to degrees. a. b. c. 6

Example 4 Draw the angle in standard form. a. b. c. d. e.
