Detailed Notes
Geometric constructions use a ruler and compass to create accurate figures. A perpendicular bisector of a line segment passes through its midpoint and meets the segment at 90°. Equal-radius arcs from the endpoints can locate the points needed to construct it. Accurate construction depends on keeping the compass opening unchanged when required.
