That could be numerous polygons: a square, a regular hexagon, a regular octagon, a regular dodecagon ...

Any regular polygon with an even number of sides could be your answer.

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

Are all squares quadrilaterals why or why not?

Yes they are. The definition of a quadrilateral is a closed figure with four sides. A square always has four congruent sides and is a closed figure. Therefore, all squares are quadrilaterals. Trapezoids, rhombuses, and rectangles are also quadrilaterals.


What is a mathematical definition of right trapazoid?

It is a closed four-sided shape with one pair of parallel sides, joined at only one end by a line which is perpendicular to both.


What have 2 parallel bases that are not polygons?

There are several cases: any 3 dimensional or more object. Since a polygon is defined as being confined to a single plane, any shape that violates the plane is not a polygon but may still have parallel bases. For cases in only 2 dimensions: Any object that has curves in addition to the parallel bases. A polygon's definition includes only straight sides. Finally, unclosed shapes can have 2 parallel bases with out being polygons even if in a single plane and made up of only straight line sides. A polygon must be closed.


What is non polyhedron?

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.http://wiki.answers.com/What_is_the_difference_between_a_polyhedron_and_a_non_polyhedron#ixzz185DDOyd9


Are rational numbers closed under division multiplication addition or subtraction?

Rational numbers are closed under addition, subtraction, multiplication. They are not closed under division, since you can't divide by zero. However, rational numbers excluding the zero are closed under division.

Are opposite sides parallel on a triangle?

Never, there are no true "opposite sides" on a triangle as each side intersects the other two at a point. Were two of the lines parallel, the triangle would be missing a point and would not be a closed shape.

How does a parallelogram triangle look?

it just doesnt exist. parallelogram is a closed shape vth opposite sides parallel adjacent angle not 90 degree. triangle is closed shape vth 3 sides.


What are properties of a rectangle?

A rectangle has four sides and four angles. A rectangle is a closed shape. All four angles of a rectangle are right angles. That is, they are 90 degrees. Opposite sides of a rectangle are the same length. Opposite sides of a rectangle are parallel. That is, if they were extended infinitely they wouldn't touch. ***Additionally, the diagonals of a rectangle are congruent (unlike other parallelograms), and they also bisect each other. While all parallelograms share the bisecting diagonals characteristic, only rectangles (and by extension squares) have congruent diagonals.***
