Reason. 1. ∠ 1 ...A radian, which is short for radius angle, is also based on the concept of a circle. If the arc length of a sector is equal to the radius, then we can say that the angle is 1 radian. If the angle is in degrees, we must use the correct symbol ′ ° ′ to show that the angle has been measured in degrees.Notice the distinction between the above examples. Example 1.1 is an unknown angle problem because its answer is a number: d = 102 is the number of degrees for the unknown angle. We call Example 1.2 an unknown angle proof because the conclusion d = 180 − b is a relationship between angles whose size is not speciﬁed. EXAMPLE 1.3.Make sure you know how to identify the different types of angles formed when two lines are cut by a transversal: The angle pairs {2, 8} and {3, 7} are alternate interior angles—you can remember this because they form a sort of “Z” shape or reversed “Z” shape.
