Final answer:
If line segment AB is bisected at point P, the measure of AP is half the length of segment AB.
Step-by-step explanation:
In geometry, if a line segment, AB, is bisected at a point P, it means that point P is exactly in the middle of the line segment. Therefore, the resulting segments AP and PB will be equal in length, which is a fundamental property of a bisecting point.
So, the length or measure of AP would be exactly half of the total length of line segment AB. If you know the total length of AB, you would simply divide that by 2 to find the measure of segment AP. For example, if AB measures 10 units, then AP would measure 5 units.
