Side 22 - ... similar rectilineal figures are to one another in the duplicate ratio of their homologous sides.
Side 44 - 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.
Side 7 - When a straight line standing on another straight line makes the adjacent angles equal to one another, each of the angles is called a right angle ; and the straight line which stands on the other is called a perpendicular to it.
Side 67 - EXERCISES. 1. Draw a line inclined at 30° and making an angle of 45° with the vertical plane ; and a plane inclined at 50° and making an angle of 65° with the vertical plane, to contain the line. 2. The horizontal trace of a plane makes an angle of 30° with the ground line ; draw the vertical trace on the supposition that the two traces really contain an angle of 65° ; thence determine the angles which this plane makes with both planes of projection.
Side 8 - A rhombus, is that which has all its sides equal, but its angles are not right angles.
Side 44 - A parallelepiped is a solid figure contained by six quadrilateral figures, whereof every opposite two are parallel.
