Succeeding Context: K is a solution of a second-order polynomial, and therefore any number which is constructible by a series of steps is the solution of a power of two minimal polynomial. Note also that \pi/3 radians (60 degrees, written 60°) is constructible. We now show that it is impossible to construct a 20° angle; this implies that a 60° angle cannot be trisected, and thus that an arbitrary angle cannot be trisected.
