Page 155 - An oblique prism is a prism whose lateral edges are not perpendicular to the planes of the bases.
Page 152 - A circle is a plane figure bounded by a curved line, called the circumference, every point of which is equally distant from a point within called the center.
Page 156 - A regular pyramid is a pyramid whose base is a regular polygon, the center of which coincides with the foot of the altitude.
Page 159 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center. The radius of a sphere is a straight line drawn from the center to the surface.

Page 158 - ... lines, parts, and masses of a subject. Concave. Curving inwardly. Cone. A solid bounded by a plane surface called the base, which is a circle, ellipse, or other curved figure, and by a lateral surface which is everywhere curved, and tapers to a point called the vertex. Its base names the cone. Thus a circular cone is one whose base is a circle. A RIGHT CIRCULAR CONE is generated by an isosceles triangle which revolves about its altitude as an axis. The equal sides of the triangle in any position...
Page 149 - The angle opposite the base is known as the vertical angle, and the vertex of this angle is called the vertex of the triangle. The altitude of a triangle is the perpendicular distance from the vertex to the base or the base produced.
Page 164 - At a given point in a given straight line, to construct an angle equal to a given angle. Let A be the given point in the straight line AB, and O the given angle.
Page 151 - A TRAPEZOID is a quadrilateral which has only two of its sides parallel ; as the quadrilateral RST U.
Page 152 - The radius of a circle is a straight line drawn from the center to the circumference, and is equal to one-half the diameter.
