it is an assignment/homework and the instructions are to construct an angle of 165 degrees.

Solving the problem …

It depends what tools you have. You can construct it with a compass for example. A compass it could be built with a pencil and some string or rope. From a line you can define the triangle by drawing two arches which intersect themselves. From this, With compass you can divide an angle of the triangle twice (each one is 60 degrees) and will obtain 15 degrees. This 15 degrees angle you subtract from a straight line (180-15=165 degrees) and you have the angle you need 🙂
