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 has exactly two adjacent right angles that is not a parallelogram?

A square because a parallelogram has two parallel sides and have two adjacent right angles but a square and a rectangle have also a two adjacent right angles.

What has adjacent sides not equal 2 pairs of congruent sides and 4 right angles?

A parallelogram

Are all angles of a parallelogram equal to 90 degrees?

No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).

What is a rectangle called tilted?

A parallelogram.Types of parallelogram:Rhomboid - A quadrilateral whose opposite sides are parallel and adjacent sides are unequal, and whose angles are not right anglesRectangle - A parallelogram with four angles of equal sizeRhombus - A parallelogram with four sides of equal length.Square - A parallelogram with four sides of equal length and four angles of equal size (right angles).

Do all squares have two parallel sides?

All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).

What shape has 2 pairs of equal sides and no right angles?

A shape that has 2 pairs of equal sides and no right angles is a kite or a parallelogram. In a parallelogram, each side is equal to the one directly opposite; in a kite, the equal sides are adjacent to one another.

A parallelogram with 4 equal sides but no right angles?

A parallelogram with four equal sides and no right angles is a rhombus.

Are the adjacent sides on a parallelogram perpendicular?

Generally no. If they are perpendicular, all four angles are right angles and the parallelogram is usually called a rectangle.

How parallelogram with four equal sides but no right Angles?

a rhombus is a parallelogram with 4 equal sides. It does not need right angles; that is a special case which is a square

Is a rhombus a parallelogram with four right angles and all sides equal in length?

No, that's a square. A rhombus is a parallelogram with 4 equal sides, but no right angles.

If a parallelogram has one right angle then all of its angles must be right?

Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.

What are the differences between a parallelogram and a rectangle?

A rectangle IS a parallelogram. However, it is a special case, since not only opposite, but also adjacent angles are equal. Since the angles must sum to 360 degrees, if they must all be equal you have 90 degrees or right angles for all of them . A rectangle is a quadrilateral with 4 right angles. A rhombus is a quadrilateral with 4 equal sides. A parallelogram is a 4-sided polygon where the opposite sides are parallel. A rectangle is a type of parallelogram, but it has the added requirement that all angles are 90°.
