How to Construct a Perpendicular Bisector of a Line Segment

The video tutorial explains how to construct a perpendicular bisector of a given line segment AB. It involves using a compass to draw arcs from points A and B, marking the intersection points of these arcs, and drawing a straight line through these points to form the perpendicular bisector, line L. The tutorial concludes by confirming that line L bisects AB at point M, making AM equal to BM.

What is the significance of the points where the arcs intersect?

What can you conclude about line L in relation to line segment AB?
