The two angle measures that can be trisected using a straightedge and compass are 0 degrees and 180 degrees. Any angle that is a multiple of these measures can also be trisected. However, it is important to note that most arbitrary angles cannot be trisected using just these tools due to the limitations established by the impossibility of certain constructions in classical geometry.
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.
The compass is used to measure angles. The straightedge is used to draw a straight line. The two items together, are used to measure and draw angles and lines in geometric drawings.

No, it is not possible to construct a cube of twice teh volume of a given cube using only a straightedge and a compass.
The first step in constructing an angle bisector using a compass and straightedge is to place the compass point at the vertex of the angle and draw an arc that intersects both rays of the angle. This creates two intersection points on the rays, which will be used in the next steps to find the bisector.
