  1. Section 3-3Constructing Perpendiculars to a Line

  2. 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.

  3. 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.

  4. Patty Paper Perpendiculars • P. 155 Investigation

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