1.4 Worksheet – Constructing Parallel and Perpendicular Lines
1. Given AB , use the midpoint construction to construct a perpendicular bisector. Label the
intersection, label congruent parts on the diagram, and list one pair of congruent or equal pieces.

2. Construct the perpendicular line THROUGH A POINT ON THE LINE. Work backwards from
the midpoint construction.

5. Construct a line parallel to the given line and through the given point.
6. Given sides of a rectangle. Construct the rectangle. (Hint: We need perpendicular lines
through A and through B).

7. If you are told that MN is the perpendicular bisector of BC where point M is on BC . Draw the
diagram and completely label it with all known relationships.
8. If you are constructing the perpendicular line through point A (A is on the line), determine the next step.
Step #1 – Place compass at point A, and create two intersections B & C on either side of point A.
Step #2 – Place compass pointer at point B and extend its measure beyond A and make an arc above
and below point A.
Step #3 -- __________________________________________________________________________
