Σελίδα 73 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center.
Σελίδα xii - A STRAIGHT line is perpendicular to a plane, when it is perpendicular to every straight line which it meets in that plane.
Σελίδα 5 - If from the foot of a perpendicular to a plane a straight line is drawn at right angles to any line of the plane, and its intersection with that line is joined to any point of the perpendicular, this last line will be perpendicular to the line of the plane. Let AP be perpendicular to the plane MN...
Σελίδα 1 - If a straight line is perpendicular to each of two straight lines at their point of intersection, it is perpendicular to the plane of those lines.
Σελίδα 59 - A truncated triangular prism is equivalent to the sum of three pyramids whose common base is the base of the prism, and whose vertices are the three vertices of the inclined section.
Σελίδα 93 - The area of the surface generated by a straight line revolving about an axis in its plane, is equal to the...
Σελίδα 71 - The volume of a triangular prism is equal to the product of the area of a lateral face by one-half the perpendicular distance of that face from the opposite edge.
Σελίδα 85 - If two triangles have two sides and the included angle of one equal respectively to two sides and the included angle of the other, the triangles are equal.
Σελίδα 47 - The volumes of two pyramids (cones) are to each other as the product of their bases and altitudes...
Σελίδα 11 - If two angles, not in the same plane, have their sides respectively parallel and lying in the same direction, they are equal and their planes are parallel. Let BA C,B'A...
