An angle of 60 degrees can be trisected using a straightedge and compass, resulting in three angles of 20 degrees each. However, a 45-degree angle cannot be trisected using these tools, as it does not yield a constructible angle with rational coordinates. This limitation arises from the fact that the trisection of a 45-degree angle leads to angles that are not constructible with straightedge and compass. Thus, while 60 degrees is trisectable, 45 degrees is not.
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.
The impossibility of trisecting an arbitrary angle using only a compass and straightedge is a result of the limitations imposed by classical geometric constructions. This conclusion is rooted in the field of abstract algebra, specifically the properties of constructible numbers and the fact that the angle trisection leads to solving cubic equations, which cannot be accomplished with just these tools. While certain specific angles can be trisected, there is no general method for all angles. This was proven in the 19th century as part of the broader exploration of geometric constructions.
Yes and the trisections will form 4 angles of 22.5
An angle of 65° can not be trisected using a compass and straight edge.

Perpendicular lines that meet at right angles is one example
You might not understand angles and shapes as well with a drawing program, even though it requires a little bit more effort with a compass and straightedge. You would just create shapes without understanding how they were made or what the postulates and theorems and stuff mean. To sum it up, each have their own problems and advantages, but using a compass and a straightedge lets you see deeper into the way shapes and angles work :) ugh I hate using a compass and straightedge in geometry lol :)>
Constructions that are impossible using only a compass and straightedge include Trisecting an angle Squaring a circle Doubling a cube

No, it is not possible to construct a cube of twice teh volume of a given cube using only a straightedge and a compass.
