УелЯдб 48 - Assuming that the areas of two triangles which have an angle of the one equal to an angle of the other are to each other as the products of the sides including the equal angles...
УелЯдб 46 - Similar cylinders are to each other as the cubes of their altitudes, or as the cubes of the diameters of their bases.
УелЯдб 4 - If a straight line is perpendicular to each of two other straight lines at their point of intersection, it is perpendicular to the plane of the two lines.
УелЯдб 49 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center.
УелЯдб 94 - Two triangles are equal if two sides and the included angle of the one are equal respectively to two sides and the included angle of the other (sas = sas). Hyp. In A ABC and A'B'C', AB = A'B', BC = B'C', and Z B = Z B'.
УелЯдб 46 - The lateral areas, or the total -areas, of two similar cones of revolution are to each other as the squares of their altitudes...
УелЯдб 6 - Theorem: If a straight line is perpendicular to one of two parallel planes, it is perpendicular, also, to the other plane.
УелЯдб 9 - ... meeting the plane at unequal distances from the foot of the perpendicular the more remote is the greater.
УелЯдб 56 - A spherical angle is measured by the arc of a great circle described from its vertex as a pole, and included between its sides, produced if necessary.
