You know how to construct the perpendicular bisector of a segment. Now, investigate how to construct a perpendicular to a line l from a point A not on l. Think about how you have used circles in constructions so far and why the perpendicular bisector construction works the way it does. The first step of the instructions has been provided for you. Discover the construction, and write the remaining steps.
Describe the steps below. Step #1 has been completed for you.[br][br]Step 1: Draw circle A: center A with radius so that circle A intersects line l in two points.
