A cylinder has two parallel congruent faces and a curved surface.
A cube satisfies that description.
A triangular pyramid * * * * * A triangular pyramid has no parallel faces. None. The correct answer is a parallelepiped (special cases: cuboid, cube).
Many 3d shapes have a corner.
The correct name for a 3D diamond shape is a rhombic dodecahedron. This polyhedron has 12 congruent rhombus-shaped faces and is a type of dodecahedron, which is a polyhedron with 12 faces. The term "diamond" is often used colloquially to describe this shape due to its resemblance to the face of a cut diamond.
No, its a triangularprism
A prism has two parallel and congruent bases in the shape of polygons. Example - a cereal box (is rectangular prism). The top and bottom are rectangles(a polygon). They are the same size and shape (congruent) and also parallel. A cube (think of six sided dice) is a special rectangular prism. Imagine a a box where the top and bottom are triangles (of the shape size and shape). This is called a triangular prism.
A cylinder has two parallel congruent faces and a curved surface.
They could be pentahedra in the form of triangular prisms or octahedra in the form of triangular antiprisms.
A cylinder or half a torus (donut), or a long tubular shape whose ends are lined up so as to be parallel..
Cylinder
Prism, which a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms.
A cylinder would seem to fit the given description that has circular parallel bases and a rounded body.
It is a three dimensional shape whose faces are rectangles. There are three pairs of congruent parallel rectangles opposite each other. A smooth brick or box are good examples.
cube
The two congruent 3D triangles were equal in shape, size, length and volume.
Any 3D shape with a constant cross-section; in other words, a 2D shape stacked on top of itself, like a triangle on a Toblerone box. But it need not be a triangular shape that is stacked. A rectangular 2-d shape would give a cuboid. Any poygonals shape can be stacked for a prism. Not a piramid, or pyramid even, which is not a prism!
