How to construct the perpendicular bisector of a segment?
Perpendicular Bisector :
When looking at a line segment, there is only one line that will pass through the midpoint that will be a constant distance between the two endpoints. This line is called the perpendicular bisector. It helps us locate the midpoint of a line segment and constructs a 90° angle.
To construct the perpendicular bisector, we first find the midpoint of the line segment and then use a compass and straightedge to draw the perpendicular line.
