Question

1. state the definition, postulate, theorem, or property that justifies the statement below. if (ab = cd), then (overline{ab}congoverline{cd}).

Explanation:

In geometry, the definition of congruent segments states that if the lengths of two segments are equal, then the segments are congruent. Here, since the lengths $AB$ and $CD$ are equal ($AB = CD$), the segments $\overline{AB}$ and $\overline{CD}$ are congruent by the definition of congruent segments.
