A 30-60-90 right triangle is one in which the three angles of the triangle 30, 60 and 90 degrees. The length of the sides of such a triangle have the ratio 1:2:square root of 3. The 1 is opposite the 30 degree angle, the 2 is opposite the 60 degree angle and the square root of 3 is opposite the 90 degree angle.
Unit of Measure - Angles are measured in degrees or radians. A degree represents 1/360 of a circle. Each degree is subdivided into 60 minutes. And each minute has 60 seconds. The basic tools used to measure angles are a protractor, compass and set square. Protractor - The protractor is a semi-circular instrument with the degrees marked from 0 to 180. There are two sets of markings; the inner scale goes from right to left and the outer scale from left to right. Compass - A compass is a hinged set of arms. One arm has a pointed end and the other holds a pencil. The compass is used to measure and construct angles. Set Square and Sextant - Set squares are of two kinds--the 90-45-45 degree angle and the 30-60-90 degree angle. They are measuring tools used in drafting and engineering. A sextant is an ancient navigating tool.

Assuming the set square has angles of 30o 60o and 90o.... You can draw a right angle without any problem. That leaves 60 degrees left to draw so - place the 60 degree corner on the junction of the 90 degrees and draw another line. This gives you a total angle of 150.
The hands of a clock at two o'clock are set at a 60 degree angle.

A set square? Only good for 30, 45, 60 amd 90 degree angles, though.
60
1. it useful in geometry 2. used for drawing a straight line It's used for drawing 30, 60 and 90 degree angles. There is also a version for 45 degree angles.

You should use a protractor.
