What are the example of a pyramid?
A polyhedron with a polygonal base and triangles for sides.
How many does a tetrahedron have?
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.
How many sides are there on a standard pencil?
A standard pencil has 6 sides.
How many sides has a myriagon got?
19999999999999
How many sides does a myriagon have?
45
What is the definition of polyhedron?
A polygon has many sides whereas a polyhedron has many faces as for example a pyramid
What is non-polyhedron?
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").
What are the flat sides of a polyhedron?
They are the faces of the polyhedron.
What is the difference between a polyhedron and a non polyhedron?
A polyhedron is a closed figure with several (planar) sides, and all its sides are planar. A non polyhedron does not have these properties, maybe it is not closed, maybe one or more of the sides is a curved surface. In some branches of topology the sides of a polyhedron cannot intersect each other.
A polyhedron with two congruent sides?
It is a polyhedron with two congruent sides: nothing more, nothing less.
Why decahedron is not a regular polyhedron?
It is not a regular polyhedron because it has unequal sides
Do 20 equal sides form a polyhedron?
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.
How many edges does a polygon have?
None because it has sides whereas a polyhedron has edges
What does the word regular polyhedron mean?
A solid figure with many sides such as a pyramid
What is a polyhedron and a prism that has 2 bases are hexagons and other faces are rectangles?
No polyhedron has five sides as a pentagon and a hexagon has six sides
What shapes go in the category of irregular polyhedra?
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.

How many vertices dose a polyhedron have?
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.
