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.
True
True
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, and the proof was provided by Wantzel in 1837.
Yes and the trisections will form 4 angles of 22.5
True
True
As a general rule, no.

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.
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.
doubling the cube
To trisect a right angle form an equilateral triangle with one vertex at the right angle and then bisect that angle of the equilateral triangle. (It is impossible to trisect a general angle using only compass and straight edge - the right angle is a specific exception.)
