Through the points A and a , draw lines parallel to wy to show the ends of the
prism . Each of the points A , B , C ' ' , & c . , represents a line perpendicular to the
vertical plane . In the plan these lines will be shown at right angles to xy ( Pr . 2 ) .

Side 193 - A cone is a solid figure described by the revolution of a right-angled triangle about one of the sides containing the right angle, which side remains fixed. If the fixed side be equal to the other side containing the right angle, the cone is called a right-angled cone ; if it be less than the other side, an obtuse-angled ; and if greater, an acute-angled cone. XIX. The axis of a cone is the fixed straight line about which the triangle revolves.
Side 123 - A straight line is said to be cut in extreme and mean ratio, when the whole is to the greater segment as the greater segment is to the less.
