Two angles that can be trisected with a straightedge and compass are 90 degrees (a right angle) and 60 degrees. The trisection of these angles results in angles of 30 degrees and 20 degrees, respectively. In general, certain angles can be trisected using these classical tools, while others cannot due to the limitations imposed by the properties of constructible numbers.
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.

The straightedge method, and the map and compass method!
To measure the length of a segment, you would use a straightedge. A straightedge provides a reference line to determine the distance between two points, while a compass is typically used for drawing arcs or circles rather than measuring lengths directly. Although a compass can help in constructing segments of a specific length, it does not measure length itself.
