How can we construct an angle of 40 degrees and an angle of 80 degrees using compass?

It is ok, I got the answer. We cannot construct it using compass, only multiples of 15 con be cnstructed in this method. Am I right?

You cannot construct a 40 and 80 degrees angle with a compass. But you always have a protractor. 

Hope it helped.
