A straight line is said to be perpendicular to another straight line when it stands
on it in such a manner that the adjacent angles are equal to each other . Ex . ABв
NOTE . — It follows that a perpendicular line is not necessarily a vertical line . 11 .

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.
