Section 3-3 Constructing Perpendiculars to a Line

Constructing Perpendiculars P. 154 Investigation You already know how to construct a perpendicular bisector. Use that knowledge to construct a perpendicular from a point to a line.

Label three random points Q, R, and S on line AB. Measure PQ, PR, PS, and PM. Which distance is shortest? The shortest distance from a point for a line is measured along the _______________ from the point to the line.

Patty Paper Perpendiculars P. 155 Investigation

Draw a large obtuse triangle on a half sheet of paper. Construct the altitude from each vertex.
