What is a polyhedron with parallel edge intersect by two parallel line?
It is unlikely that the question is about a polyhedron which is a 3-dimensional solid bounded by polygons. The minimum number of edges for a polyhedron is 6: the question appears to suggest just 4.
What are the definitions of the prism and pyramid?
A prism isa polyhedron- that is, 3-dimensional shape bounded by polygons. It has two parallel bases that are identical polygons. The corresponding sides of these polygons are joined together by quadrilaterals.A pyramid is also a polyhedron. It has a polygonal base of n sides and n triangles, attached to each of the sides of the polygon, that meet at an apex above [or below] the plane of the polygon.AA prism isa polyhedron- that is, 3-dimensional shape bounded by polygons.

Why are cylinders and cones not considered to be a polyh?
Polyhedra are 3-dimensional shapes bounded by polygons. Polygons are flat [plane] shapes bounded by straight lines. So a polyhedron cannot have any curved faces.
How are a paralleogram pentagon and a square alike?
They are all polygons: two-dimensional shapes, bounded by straight lines.
What does polyheadron mean?
I think you mean polyhedron...if that's what you mean then...its a three dimensional object bounded by polygons, with each edge shared by exactly two polygons
How are hexagons and hexahedrons different?
A hexagon is a plane (2-dimensional) figure whereas a hexahedron is a solid (3-dimensional) shape. A hexagon is bounded by six straight lines whereas a hexahedron is bounded by six polygons.
What shapes are quadrangle?
squares, rectangles, trapezoids, rhombuses
What all polygons look like and the name?
Polygons are closed two dimensional shapes which are bounded by three or more straight lines. There are infinitely many of them so it is not possible to name them all.
Is A polyhedron is a two dimensional solid bounded by the polygon all regions find by intersecting planes?
No, a polyhedron is a three-dimensional solid bounded by polygonal faces. Each face is a flat polygon, and the edges of these polygons meet at vertices. The term "two-dimensional solid" is a mischaracterization, as polyhedra occupy three-dimensional space.
What are the shapes of a parrallelogram?
A parallelogram is a closed 2-dimensional shape bounded by two pairs of parallel sides.
Are pyramids polygons cylinders or prisms polyhendrons?
A polygon is a plane (2-dimensional) object bounded by straight lines. A polyhedron (not polyhendron!) is a solid (3-dimensional) object bounded by polygonal faces. So, pyramids and some prisms are polyhedra. A cylinder is a type of prism but, because two of its faces are circular, those faces are not polygons. As a result a cylinder is not a polyhedron.
Why is a cone not called a polyhedron?
A polyhedron is a solid object bounded by polygons. Polygons are plane shapes [bounded by straight lines]. The curved surface of a cone is not a polygon and so the cone is not bounded by polygons and therefore, a cone is not a polyhedron.
