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.

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.
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.
That's a classic problem that's been around for a very long time.It's been proven that it's not possible to trisect any angle in generalwith those tools, although there are a few specific angles, like aright angle, for which it can be done.
Yes! It is! I'm not perfectly sure how, but my father has, in fact, done this.
