A polyhedron is a solid shape with many sides. The word "polyhedron" does not specify a number of sides.
A polyhedron with a polygonal base and triangles for sides.
A tetrahedron has 4 vertices and 4 sides. Each side is an equilateral triangle. * * * * * Each face is an equilateral triangle only if it is a regular tetrahedron; there is no reason to assume it is.
A standard pencil has 6 sides.

A polygon has many sides whereas a polyhedron has many faces as for example a pyramid
A polyhedron has "many sides" (by definiton). The only 3-D shape which does not have "many sides" is a sphere (which technically only have one "side").
They are the faces of the polyhedron.
NO!!! A triangle is a 2-dimensional shape of three sides; archaically a 'trigon'. A polyhedron is a 3-dimensional solid of many sides.
It is a polyhedron with two congruent sides: nothing more, nothing less.
It is not a regular polyhedron because it has unequal sides
A solid figure with many sides such as a pyramid
No. A polyhedron is 3 dimensional. You have a regular polygon, regular because the sides are equal. If you asked about 20 surfaces, then it would be a polyhedron.
No polyhedron has five sides as a pentagon and a hexagon has six sides
Any number greater than or equal to 4. A polyhedron is a generic term meaning a [3-dimensional] shape with many plane sides. There are some other requirements also, but the point is that the term does not specify how many sides or vertices.
If, by "sides" you mean faces, then the answer is a pentahedron.
A polyhedron is a plane shape, enclosing a single space, which is bounded by straight lines.If ALL angles and ALL sides are equal, then it is a regular polyhedron. All other polyhedra are irregular.Note that if any of the sides is not straight then the shape is not a polyhedron at all, and so cannot be an irregular polyhedron.A polyhedron is a plane shape, enclosing a single space, which is bounded by straight lines.If ALL angles and ALL sides are equal, then it is a regular polyhedron.
