"Measuring" is not permitted. You are granted access only to an idealized compass and straight edge. There's a mobile game called Euclidea based on this which I'd recommend.

Oooh. I was imagining a compass like you're given in school, with labels on it, and ditto a ruler. :-)

That would be a protractor, which would be allowed if there were 340 degrees in a circle.
