Question

rewrite the definition of the term as a biconditional statement. see example 5
the midpoint of a segment is the point that divides the segment into two congruent segments.
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. For the mid - point, if a point is the mid - point of a segment, then it divides the segment into two congruent segments, and if a point divides a segment into two congruent segments, then it is the mid - point of the segment. Similarly for adjacent angles, if two angles are adjacent, then they share a common vertex and side and have no common interior points, and if two angles share a common vertex and side and have no common interior points, then they are adjacent.

Answer:

1. A point is the midpoint of a segment if and only if it divides the segment into two congruent segments.
2. Two angles are adjacent if and only if they share a common vertex and side but have no common interior points.
