In general, you will need to use a protractor and measure them.
It is easy to draw an equilateral triangle without a protractor. That gives a 60 degree angle. It is then simply a matter of bisecting the 60 degree angle, using an unmarked rule and compass, to get a 30 degree angle.
Using the formula: (number of sides -2)*180 = sum of interior angles
One way is to use a protractor. There are others
I used a protractor to find the measure of the angle.

i don't know it this helps, but the sum of the angles in a quadrangle is 360 !
use the sun and silhoutte

A protractor.

The sum of the angles in a quadrangle is 360 degrees, whatever the side lengths.
Use a protractor.
