measure of the angle. If we sweep in a clockwise direction, then −mis deļ¬ned to be the degree measure of the angle. So, in Figure 15.3, the left-hand angle has positive degree measure while the right-hand angle has negative degree measure. Simple examples would be angles like the ones in Figure 15.5.

1-3 Measuring and Constructing Angles You can use the Protractor Postulate to help you classify angles by their measure. The measure of an angle is the absolute value of the difference of the real numbers that the rays correspond with on a protractor. If OC corresponds with c and OD corresponds with d, m DOC = |d – c| or |c – d|.

Section 5.2 Angles 351 Radians The radian measure of an angle is the ratio of the length of the circular arc subtended by the angle to the radius of the circle. In other words, if s is the length of an arc of a circle, and r is the radius of the circle, then radian measure s r = If the circle has radius 1, then the radian measure corresponds to the length of the arc.
