No, and the proof was provided by Wantzel in 1837.
Yes and the trisections will form 4 angles of 22.5
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.

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, it is impossible to trisect any arbitrary angle using only a compass and straightedge. This was proven in the 19th century as part of the broader study of constructible numbers and geometric constructions. While some specific angles can be trisected through these methods, the general case cannot be solved with just a compass and straightedge.
No
You don't need advanced algebra to prove that it is impossible to trisect a line segment using only a straight edge and a compass: anyone knows that you will also need a pencil! And one you have that then there are plenty of easy ways to do it.
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.
