A plane is perpendicular to a plane, when the straight lines drawn in one of the planes perpendicular to the common section of the two planes, are perpendicular to the other plane. 5. The inclination of a straight line to a plane... An elementary course of mathematics - Page 1by Samuel Hunter Christie - 1847Full view - About this book
