Here is point A on line l and point B that is not on l.

Do the following:

1. Create a line through A and B extending in both directions. Label this line p.

2. Create a circle centered at A with radius AB. This circle intersects with line l in 2 places. Label the intersection point to the right of A as C.

3. Create a circle centered at B with radius BA. This circle intersects with line p at A and 1 other point. Label the new intersection point as D.

4. Create a circle centered at with a radius of length . This circle intersects with the circle centered at in 2 places. Label the intersection point to the right of as .

5. Using a different colored pencil, create a line through and extending in both directions.
