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

Do all triangles have two acute angles?

INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.

Do triangles have at least one right angle?

Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles

Can triangles have two obtuse angles?

no think about it

Are there triangles with two obtuse angles?

no, it is impossible

Does an acute triangle have obtuse angles?

No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.

What is the triangles name if two of the angles are 15 and 47 degrees?


What types of triangles have at least two acute angles?

All triangles need at least two acute angles

Some triangles have two obtuse angles and one acute angle?

Spherical triangles as on the earth's surface.

How are acute and obtuse triangles the same?

Similarities between these and all triangles are:They all have 3 sides and 3 angles. The sum of the three angles adds up to 180°.An acute angle is less than 90 degrees. An acute triangle has all three sides are acute.An obtuse angle is more than 90 degrees. An obtuse triangle has one angle which is obtuse, and because of the 180° rule above, the other two angles will be acute.So all triangles will have at least two acute angles.

Do triangles have two obtuse angles?

No. All angles in a triangle must add up to 180 degrees. An obtuse angle is over 90 degrees. So, two obtuse angles would put you at 182 degrees, minimum.

Which triangle has two acute angles and one obtuse angle?

If you are classifying triangles by their angles, an obtuse triangle has one obtuse angle and two acute angles. A triangle can have at most one obtuse angle. If the two acute angles are congruent, the triangle would also be isosceles.

When classifiying triangles by angles obtuse triagles have one obtuse angle and what two other angles?

An obtuse angle is greater than 90° (and less than 180° ) The other two angles therefore total less than 90° and so both must be acute angles.
