draw a base and use this to draw an equilateral triangle each angle of an equilateral triangle adds up to 60 degrees. To have an angle of 120 degree use this angle and then draw another side of a triangle next to it to get a 120 degree angle.
Construct an equilateral triangle which will have 3 equal interior angles of 60 degrees and 3 equal exterior angles of 120 degrees
120 degrees is an obtuse angle
With a protractor
A 40 degree acute angle can be constructed with a straight edge and a protractor.

120 degrees is an obtuse angle
With a protractor
Use a straight edge and a protractor to construct an acute angle of 65 degrees
A 120 degree angle is an obtuse angle. This means that the angle is between 90 and 180 degrees.
A 40 degree acute angle can be constructed with a straight edge and a protractor.
Use a protractor.
An obtuse angle
Use a protractor or bisect a 45 degree angle with a compass and a straight edge
by 60 degree and 90 degree
