Aadori --. The step included in the construction of perpendicular lines using a point on the line is make arcs above and below the given line with a compass.
Any point on the perpendicular bisector of a line segment is equidistant from the endpoints of. the line segment. Mathematical Modeling Exercise. You know how to construct the perpendicular bisector of a segment. Now, investigate how to construct a perpendicular. to a line ðµ from a point  not on ðµ.
