First draw a horizontal straight line a b
Put compass point on a (open compass approximately half the length of line a b - note: ensure the compass is not altered throughout the following). Draw an arc that cuts line a b at c.
Put compass point on c and draw an arc from a to cut the first arc at d.
Draw a straight line through a d to form a 60 degree angle.
For a 120 degree angle, put compass point on dand draw an arc from a to cut the first arc at e.
Draw a straight line from a through e to give a second angle of 60 degrees: 60 + 60 = 120 degrees.

How do you construct angles without using protractor?
you might not be able to construct all the angles, but using a compass you can construct some angles by constructing angular bisectors. eg:construct angular bisector of straight line i.e; 180 degrees it gives 90 degrees
How do you construct a 10 degree angle with a compass?
A 10 degree angle cannot be constructed using only a compass and straight edge.
Is it possible to construct a cube of twice the volume of the given cube using only a straightedge and compass?
No, it is not possible to construct a cube of twice teh volume of a given cube using only a straightedge and a compass.
How do you construct a 35.5 degree angle using a compass?
With a straight edge and a protractor
How do you construct 130 degree using ruler and compass?
You cannot, you must use a protractor.
