You can't create an arc with a straight edge.  That rules out one.

To construct parallel lines, I might construct a perpendicular line, twice.  This might be construed as copying an angle, I suppose.  Not really clear from those choices.

It isn't necessary to keep pinging me.  I'll see it and get back as soon as I can.

Can you construct a line perpendicular to a given line?

tkhunny · Answer

Do that twice and you have a pair of parallel lines.  Does any part of that process sound like it is described in the problem statement?  I'm not really seeing it.

Tough call.  I would be interested to know the "correct" answer and how it applies as it is written.
