two intersecting lines create four angles with the same vertex, labeled A,B,C,and D. angle b is adjacent to<a and <c
If angle B is adjacent to angle A and angle C, then angle B must be the common angle formed by the intersection of the two lines, while angles A and C would be the angles formed by the lines on opposite sides of angle B.
Thus, we can visualize the situation as follows:
D

A -- B -- C

In this diagram, angle B is adjacent to angles A and C, and angle D is the remaining angle formed by the intersection of the two lines.
