are the bases of a prism congruent
Teacher professional development and classroom resources across the curriculum. apex. in a pyramid, the vertex at which all lateral faces meet. base. in a prism, the two congruent, parallel faces at the top and bottom; in a pyramid, the regular polygon that is not a lateral face. congruent. having the same size and shape. prism - a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms. polyhedron - a solid figure bounded by plane polygons or faces. parallelepiped, parallelepipedon, parallelopiped, parallelopipedon - a prism whose bases are parallelograms. Geom. a solid having bases or ends that are parallel, congruent polygons and sides that are parallelograms. 3. Crystall. a form having faces parallel to the vertical axis and intersecting the horizontal axes. A polyhedron in which the base is a polygon and the lateral faces are triangles with a common vertex. The intersection of two lateral faces is a lateral edge. The intersection of the base and a lateral face is a base edge. The altitude, or height, is the perpendicular distance between the base and the vertex.

If your prism is a 'right' prism and your pyramid is a 'triangular' pyramid, then their volume formulae are, respectively: V = Ah, and V = (1/3)Ah where 'A' is the area of the base and 'h' is the height. If the bases areas and heights are congruent (i.e. the same), then the volume of the pyramid is 1/3 the volume of the prism. If you have different types of prisms or pyramids, the relationship between them may be different. There are many varieties of prisms and pyramids. If your prism is a 'right' prism and your pyramid is a 'triangular' pyramid, then their volume formulae are, respectively: V = Ah, and V = (1/3)Ah where 'A' is the area of the base and 'h' is the height. A polyhedron with two congruent faces, called bases, that lie in parallel planes. The other faces, called lateral faces, are parallelograms formed by connecting the corresponding vertices of the bases. The segments connecting the vertices are lateral edges. The altitude, or height, of a prism is the perpendicular distance between its bases. 1. a solid figure whose sides are parallel and whose two ends are the same in shape and size. 2. a glass object of this shape, usually with triangular ends, which breaks up a beam of white light into the colours of the rainbow. prismaties مَوْشوري، مَنْشوري призматичен prismático hranolový Prismen-...
