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
Love triangle Love triangle A love triangle (also called a romantic love triangle or a romance triangle or an eternal triangle) is usually a romantic relationship involving three or more people. While it can refer to two people independently romantically linked with a third, it usually implies that each of the three people has some kind of relationship to the other two. The relationships can be friendships, romantic, or familial. The 1994 book "Beliefs, Reasoning, and Decision Making" states, "Although the romantic love triangle is formally identical to the friendship triad, as many have noted their actual implications are quite different...Romantic love
