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.

It is possible to trisect any angle using only a compass and a straightedge true or false?

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.


Is it possible to trisect any given angle using a straightedge and compass?

No, and the proof was provided by Wantzel in 1837.

Using a compass and a straightedge is it possible to construct Rays to trisect any angle true or false?

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.

When you trisect a right angle you first construct what kind of triangle?

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.)


If I have an answer to the trisect any angle geometry question how can I discover if I am right or wrong?

First things first, the actual statement isn't "you can't trisect an angle" but rather "you can't trisect one with only a compass and straightedge." Some angles can be easily trisected--a 90-degree angle trisects into 30-degree segments-but to do it you need a protractor. Anyway, to check your work measure the angle you trisected and divide by three. If your trisections match, you got it right.
