...a number, which is absurd : hence, p cannot enter into the function <p, and we have simply C = 0 : (A, B). This formula already proves that if two angles...angle of the former must also be equal to the third angle of the latter ; and this granted, it is easy to arrive at the theorem we have in view. First,...
