Unit 3 Lesson 2 & 10,11: Constructions

Question

Construct a line perpendicular to the given line through point A, NOT on the line.

Answer 1

First, read the answer for point A on the line.

Step 1. Determine the solution strategy. Every point on the perpendicular will be equidistant from points E and F (not yet determined) that are on the original line.



Step 2. Create points E and F. Measure an equal distance, n, from A to E and from A to F.

Step 3 Find another point G (also not on the line), that are an equal distance n from points E and F,

Step 4. Draw the perpendicular line. It goes through A, and G.
