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

If two lines are cut by a transversal to form pairs of congruent corresponding angles congruent alternate interior angles or congruent alternate exterior angles then what are the lines?

The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.

What is the converse of parallel lines conjecture?

If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.

Are alternate interior angles congruent?

Only if the lines cut by the transversal are parallel.

Are alternate angles congruent?

Yes. Alternate interior and alternate exterior angles are congruent.

If two parallel lines are cut by a transversal then the alternate interior angles are always?


Uses of parallel lines cut by a transversal?

There's lots of useful things you can discover when parallel lines are cut by a transversal, most of them having to do with angle relationships. Corresponding angles are congruent, alternate interior angles are congruent, same side or consecutive interior angles are supplementary, alternate exterior angles are congruent, and vertical angles are congruent.

If alternate interior angles are congruent than lines are parallel what is it called?

It is the transversal line that cuts through parallel lines creating alternate equal angles.

Alternate interior angles are?

they are congruent i think

What is a line that intersects parallel lines?

a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.

If alternate interior angels are congruent then the lines are?

Then the lines are parallel to each other and the alternate equal angles are created when a transversal line cuts through parallel lines.

Are all alternate interior angles congruent?

Sometimes they are.

Are the alternate interior angles of two parallel lines cut by a transveral always interior?

Yes. "Alternate interior" angles are always interior. Angles that are not interior as well as alternate are never accurately described as "alternate interior" angles.
