We use one of those angles to get the desired 60 degree result. I feel that this might help in improving anyone’s geometrical skills. To construct 45 degree angle, first we draw 90 degree angle and its done in the following steps: 1). These angles must be constructed with help of COMPASS and SCALE i.e. Constructing Angles of 60º, 120º, 30º and 90º In this section, we will consider the construction of some angles with special sizes. Step 1: Draw the arm PQ. Constructing a … This construction works by creating an equilateral triangle. First you have to draw 60 degree angle by compass and ruler then over the 60 degree angle you have to draw 20 by compass and ruler degee angle. Then draw a second line out from the point at 80 degrees on the compass. Share 1. After watching the tutorial below you will be able to draw any angle including 60 degree.
