A and B are the sides of a right triangle that aren't directly across the right angle. C is the hypotenuse. (This only applies to right triangles).

Also, one that does pertain to all triangles is the well-known Law of Cosines, one used to develop the Pythagorean Theorem:

c2 = a2 + b2 - abcos(A), where "c" is the hypotenuse, "b" is one side, "a" is another, and "A" is the angle on the opposite's side. (Between the opposite and the adjacent).

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
