Using a compass and straightedge, it is not possible to trisect any arbitrary angle. This limitation is a result of the algebraic properties of angles and the fact that angle trisection involves solving cubic equations, which cannot be done with just these tools. However, certain specific angles can be trisected using these methods, but a general solution for all angles is impossible. This was proven in the 19th century as part of the broader study of constructible numbers.
True
True
No, and the proof was provided by Wantzel in 1837.
False. It is not possible to trisect any arbitrary angle using only a compass and straightedge, as proven by Pierre Wantzel in 1837. While some specific angles can be trisected using these tools, the general case of angle trisection is one of the classic problems of ancient geometry that cannot be solved with these methods.
Yes and the trisections will form 4 angles of 22.5

Yes, it is possible to trisect a line segment using a straightedge and compass. To do this, you can first draw two circles with the endpoints of the segment as centers and a radius equal to the length of the segment. By intersecting these circles and connecting the intersection points, you can create a series of segments that can be divided into three equal parts, effectively trisecting the original line segment.
False. It is impossible to trisect any angle using only a compass and straightedge, as proven by Pierre Wantzel in 1837. While some angles can be trisected using these tools, the general case for all angles cannot be achieved through classical construction methods.

No
to construct an angle of 20 degrees all you have to do is to trisect an angle of 60degrees
