Special Angles Certain angle pairs are given special names based on their relative position to one another or based on the sum of their respective measures. Adjacent angles Adjacent angles are any two angles that share a common side separating the two angles and that share a common vertex. In Figure 1, ∠1 and ∠2 are adjacent angles.
