Use a protractor to measure the angle. Divide that number by 3 and that is the required angle. In general, an angle cannot be trisected using a compass and straight edge.
A compass and straight edge are used to create a polygon but do not limit the number of sides of the polygon created. You have to decide that separately, then use the compass and straight edge to make what you decide on.
being an archetect requires a compass, straight edge and many other tools
A ruler has markings, a straight edge does not. In "straight edge and compass" constructions, you are not allowed to mark the straight edge. Things that are impossible using only a straight edge and compass are possible if markings are allowed (for example, it's possible to trisect an angle using a marked straight edge).
False
45 degree and a 90 degree angles
An angle of 65° can not be trisected using a compass and straight edge.

Any angle can be bisected using a compass and a straight edge.

A drawing created using a compass and straight edge is called a construction.See http://en.wikipedia.org/wiki/Compass_and_straightedge_constructions
A geometrical construction can be made with with a straight edge and a compass.
By bisecting a 15 degree angle with a straight edge and a compass.
False
A 90 degree angle can be bisected into two 45 degree angles with a compass and straight edge The diagonals of a square bisect their opposite corners into 45 degree angles
