PROBLEM:
Two angles share a common side and a vertex.

ANSWER:
Two angles that shares a common side and a vertex are called adjacent angles.
Angles are not adjacent if:
• the given angles overlap
• the given angles shares only a vertex
• the given angles shares only side and not the same vertex

> See the attached picture for the representation of adjacent angles. Angles 1 and 2 are adjacent angles.
