A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What shapes does a tetrahedron have?

A tetrahedron is a four sided polyhedron. Each face is a triangle. If it is a regular tetrahedron, then each face is an equilateral triangle.

Is there a difference between a regular tetrahedron and a non-regular tetrahedron?

Yes. A tetrahedron is a closed 3-d shape with 4 triangular faces. In a regular polygon, each of these is an equilateral triangle.

What is the formula to find the surface area of a tetrahedron?

It depends on whether or not the tetrahedron is regular. There is nothing in the question to indicate that it might be regular. In that case the easiest way to calculate the surface area is to sum the areas of each of its 4 faces.

How many vertices has a tetrahedron got?

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.

Does a tetrahedron have perpendicular faces?

No and Yes A regular tetrahedron does not have any faces that are perpendicular to each other. (Regular in this sense means all edges are equally long - all faces are equilateral triangles)You can construct a irregular tetrahedron with two or three perpencdicular faces. To make such a tetrahedron with three faces perpendicular, simply cut the corner of a cube.

How do you find lateral area of a regular tetrahedron?

If the length of each edge is s cm then the area of each face is sqrt(3)*s/4 square cm. Since there are 4 such faces, the total area is sqrt(3)*s cm2.

What is the volume of a regular solid?

There are a number of regular solids each with a different shape. The simplest is a cube, which has a volume equal to the length of one edge cubed.

How do you place four points equidistant from each other?

you cannot do this on the plane. try proving this yourself. but a regular tetrahedron in space for example is an example where there four points equidistant from each other.

How many faces are there in a tetrahedron?

Tetrahedron in geogmetry is composed of four triangular faces, three of which meet at each vertex.

How do find the volume of a polyhedron?

first, find the volume of each shape that is in the polyhedron. then you add all of them together.

How can you find out if a figure has the same volume?

By comparing the volume given to each figure.

What are the special features of a tetrahedrom?

Tetrahedron: It is the smallest "regular solid" (Edges=Faces+Corners-2), 4 faces, each one an equilateral triangle. 4 corners
