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

Is it true that an isosceles triangle can be acute or obtuse?

Yes, it is true that an isosceles triangle can be acute or obtuse. As long as a triangle has two equal angles and two equal sides, it is isosceles. That situation can occur in both acute (all angles less than 900) and obtuse (one angle more than 900) triangles. Examples are a triangle with the angles being 75-75-30 degrees (acute) and one having angles of 120-30-30 (obtuse). Of course the sides of the angles that are equal would also be equal, so both examples are of isosceles triangles.


What is the least number of angles an acute triangle can have?

All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.


What are the angles of an isosceles triangle?

They can be any size. The only unchanging 'fact' which is true about all isosceles triangles is that two of them are equal.


Is it true that Acute triangles have no angles whose measures are greater than 90 degrees?

True


Are some isosceles triangles equilateral triangles?

Yep. All equilateral triangles are isosceles triangles.


Can an Isosceles triangles may be obtuse or acute but never right?

Not true. A triangle with angles of 90, 45 and 45 is a right angled isosceles triangle. If you take a square piece of paper and fold it in half - from corner to corner - you will get this shape.


Is it true that all isosceles triangles can be equilateral triangles?
