Question

rewrite the definition as a biconditional statement. adjacent angles are two angles that share a common vertex and side but have no common interior points.

Explanation:

A biconditional statement combines a conditional statement and its converse. Here, we need to state that if two angles are adjacent, then they have the given properties, and if two angles have the given properties, then they are adjacent.

Answer:

Two angles are adjacent if and only if they share a common vertex and side but have no common interior points.
