1. the initial side of an angle measure is usually the positive x-axis. Finding the measure of an angle given arc length and radius 01:52 2.56 MB 94,275. 110 3. - 250 2. Angles are also formed by the intersection of two planes. Then, we can decide if we want to add or subtract multiples of 360 or of 2 depending on whether we want to obtain a positive or negative . Two or more angles are said to be co-terminal when they have the same initial and terminal sides. We can also use our knowledge of reference angles and ordered pairs to find the values of trig functions of angles with measure greater than 360 degrees. The angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction.
