Question

When constructing perpendicular lines with a compass and straightedge, how should you start the construction

Answer 1

The information at the link will help. Take a look.

I am wondering if you are constructing a line perpendicular to a given line at a point on that line,

OR

if you are constructing a line perpendicular to a given line from a point outside that line.

The constructions would be different.
