rectangular pyramid
A rectangular-based pyramid.
A pyramid.
It is a three dimensional shape bounded by polygonal faces (a polyhedron) which has a uniform triangular cross section, parallel triangular bases, and the remaining faces are rectangular.
A 3-dimensional shape. 5 plane faces: 3 rectangular, 2 triangular. Triangular faces parallel to one another. 6 vertices 9 edges
triangular prism
a triangular prism
A shape with 5 sides is a pentagon.However, the term face is only applied to three-dimensional forms,and a shape (solid) with 5 faces is a pentahedron.There are no regular pentahedrons. The two forms are the square pyramid and the triangular prism. The former has 4 triangular sides and a square or rectangular base; the latter has 3 rectangular (or square) faces and two triangular ends.
A triangular pyramid.
A triangular dipyramid.
A triangular prism has two triangular faces, a rectangular prism does not have any.
triangular prism
A net that forms a triangular prism consists of two triangular faces and three rectangular faces. The triangular faces serve as the bases of the prism, while the rectangular faces connect the corresponding sides of the triangles. When folded along the edges, the rectangles connect the two triangles to create the three-dimensional shape of the prism.
