1. A point that divides a segment into two congruent segments is a midpoint.
2. If a point does not divide a segment into two congruent segments, it is not a midpoint.
3. This statement is not reversible.
4. A point is a midpoint of a segment if and only if it divides the segment into two congruent segments.
