...PNN' and M'Q'Q mutually equilateral, and ZM'Q'Q = Z.PNN'. Finally, now, the triangles PNQ and M'Q' N' have two sides and the included angle of one equal respectively to two sides and the included angle of the other, and ZM'N'Q' = Z.PQN. But the angle M'N'Q' is a right angle. Therefore PQN is a right... ## Solid Geometry
