Angle trisection with coefficients in the field generated by these numbers. Therefore, any number that is constructible by a sequence of steps is a root of a minimal polynomial whose degree is a power of two. Note also that radians (60 degrees, written 60°) is constructible. The argument below shows 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. Denote the set of rational numbers by . If 60° could be trisected, the degree of a minimal polynomial of over would be a power
What If... (web series) around characters from two of the three series meeting each other and interacting in a shared alternate reality, not in continuity with any of the series. Each episode features two cast members from either "General Hospital", "All My Children", or "One Life to Live". The following is a list of featured cast members. What If... (web series) What If... is an American web series that acts as a crossover among three ABC soap operas, "General Hospital", "All My Children" and "One Life to Live". The ten-part series was originally streamed on ABC.com from July 12 to August 30, 2010. It
