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.

To measure an angle accurately, use a protractor. Place the center of the protractor at the vertex of the angle. Align one side of the angle with the 0-degree mark on the protractor. Read the measurement where the other side of the angle intersects the protractor.
