5: Construct the Perpendicular Line Through a Point on the Line
Construct a Perpendicular Line Through a Point on the Line
Given
Construct: The line perpendicular to through point B
Procedure:
1. Open your textbook to page 381. Follow the directions for construction 5. Your points will be named differently than in the textbook.
Alternatively:
1. Make a circle centered at B with a radius of AB.
2. Mark both points of intersection (A is already marked. Label the other point with the intersect tool). You now have B as the midpoint of segment AC.
3. Now that you have located the midpoint, make a perpendicular bisector through segment A (as you did in construction 4).
