yes. to be and acute angle, all angles must be acute. Obtuse angles only one angle has to be obtuse. Right angles only need one too. Acute has to have every angle to be acute, if one angle is obtuse or right, it's automatically no an acute Angle anymore.

A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.

A right triangle has one angle a right angle (90o) An obtuse triangle has one angle an obtuse angle (> 90o) An acute triangle has all angles acute (< 90o)

No it is impossible for a right triangle to have an obtuse angle therefore it will have one right angle and two acute angles.

No

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.

None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)

If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse triangle.

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.

The triangle that has one obtuse angle and one acute angle is called a scalene triangle.I hope that helped!! : { )I also hope you like my mustache man. (above)

No

A triangle is not an angle. A triangle is made of three angles. -- All three of them can be acute, but they don't need to be. -- One of them can be obtuse but doesn't need to be. -- One of them can be a right angle but doesn't need to be. -- If any angle in the triangle is right or obtuse, then the other two need to be acute.
