How to construct a 75-degree angle
The Protractor
It is a semi-circular disc used to draw and measure angles. It is graduated from 0 to 180 degrees and can be directly used to measure any angle within the range. It has two sets of markings, 0 to 180 degrees from left to right and vice versa.
For constructing angles of any given measure, be it an acute, an obtuse or a right-angle, the simplest method is by using a protractor. Let us say, you are asked to construct an angle of 120 degrees. The required steps are:
Draw a line segment BC, which is one of the arms of the angle that is to be constructed.
Place the protractor with its point O on the point B of the line segment BC.
Align OQ along the edge BC.
The protractor has two-way markings. We consider the scale which has 0 degrees near point C for construction. Mark point A next to the 120 degrees mark on the scale.
Join points A and B. ∠ABC = 120 degrees is the required angle.
