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 any pair of perpendicular lines are coplanar?

Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.

Do spheres have 3 pairs of perpendicular lines?

Spheres do not have any perpendicular lines.

What is a pentagon and a rhombus perpendicular lines and parallel?

A pentagon can have 0, 1 or 2 pairs of parallel lines. It can have 0 to 4 lines perpendicular to an adjacent line. A rhombus must have two pairs of parallel lines and none of them may be perpendicular to any other.

Are any two lines always coplanar?

No, not always. Skew lines are never coplanar, but parallel lines are.

How many pairs of perpendicular lines does a triangluar prism have?

It need not have any. A right triangular prism has 12 pairs but could have 14.

WHAT SHAPE does not have any pairs of perpendicular lines?

a triangle, pentagon and that's all i can think of * * * * * A right angled triangle has a pair of perpendicular lines! Likewise, a pentagon can have a pair. A circle, ellipse etc do not.

What are perpendicular and parallel lines on a polygon?

A polygon need not have ANY perpendicular or parallel lines. For example, consider an equilateral triangle. It can happen that two sides of a polygon, extended if necessary, meet at a point where they form a 90 degree angle. Those two lines are perpendicular. There may be pairs of lines such that, no matter how far you extend them in either direction, they will never meet. Such lines are parallel. A triangle cannot have parallel lines but it can have perpendicular lines. Any polygon of 4 or more sides can have sides that are perpendicular or parallel (or some of each).

What makes two lines perpendicular?

Perpendicular lines are any two lines that intersect at a 90 degree angle.

How is perpendicular lines similar to intersecting lines?

Perpendicular lines are lines that cross at right angles. Intersecting lines can cross at any angle.

Is the segment where perpendicular lines intersect?

Any two intersecting lines (including perpendicular lines) will intersect at a single point.

Which figure contains perpendicular lines and parallel lines?

Any polygon with four or more sides can have perpendicular and parallel lines.

How do perpendicular differ from intersecting lines?

Perpendicular lines are a subset of intersecting lines. The only difference is that perpendicular lines intersect at an angle of 90o, whereas intersecting lines can converge at any angle.

Which kind of shape has perpendicular lines?

Any polygonal shape, other than a triangle can have perpendicular lines.

How are perpendicular lines and intersecting lines alike and how are they different?

Some intersecting lines are perpendicular lines.Take any old pair of intersecting lines. If the angles at the intersectionhappen to be 90 degree angles, then the lines are perpendicular lines.

Can two lines be parellel perpendicular and intersecting at the same time?

No. If the lines are parallel they will never meet or intersect at any point. If the lines are perpendicular they do intersect, but perpendicular lines are a special case of intersecting lines. Perpendicular lines are exactly 90 degrees from each other. Intersecting lines do not haveto be perpendicular... but perpendicular lines are always intersecting.

How are perpendicular lines similar and different to intersecting lines?

Perpendicular lines are specific kinds of intersecting lines. They both cross paths. Intersecting lines can cross paths in any way, but perpendicular lines have to cross at right angles.

Does a pentagon have perpendicular line?

yes they do. they have a perpendicular line. * * * * * No, a pentagon, as in a regular polygon does not have perpendicular lines. An irregular pentagon could, and you can always add perpendicular lines to any shape.

What are lines that lie in the same plane?

They are coplanar. ANY 2 lines would be coplanar, however a third line can be outside of the plane. just like 3 points will designate a plane and a triangle

What is a coplanar in math?

A set of points, lines, line segments, rays or any other geometrical shapes that lie on the same plane are said to be Coplanar.

Intersecting lines are perpendicular?

Not necessarily. Lines can intersect at any angle. They are only perpendicular when they intersect at 90 degree angles.
