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.
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
A 10 degree angle cannot be constructed using only a compass and straight edge.
No, it is not possible to construct a cube of twice teh volume of a given cube using only a straightedge and a compass.
With a straight edge and a protractor
You cannot, you must use a protractor.

With a straight edge and a protractor
Yes, it is possible to construct an angle measuring 7.5 degrees using a compass and straightedge. This can be done by first constructing a 15-degree angle, which is achievable through a combination of bisecting angles. By bisecting a 15-degree angle, you can obtain the desired 7.5-degree angle. This method relies on the principle that angle bisection is a fundamental constructible operation.
You cannot, you must use a protractor.
Construct 2 perpendicular lines which will meet at 90 degrees then by bisecting this angle wll give a 45 degree angle
