I don't think your construction method is correct.

1) The line from the point should be perpenducular to the line CD

2) you should then mark two spots above and below E respectively, on the perpendicular line.

3) from these point you should make parts of circles that intersect, on both sides of the perpendicular line to get two points, from which you can draw the line.

Hi.

I hope the pictures below explain it.
