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)

A triangle has at two acute angles and the third angle is either an acute angle, a right angle or an obtuse angle.

A triangle can have one obtuse angle and two acute angles. The sum of all three angles must equal 180 degrees.

If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)

Nope, only one obtuse angle in a triangle is possible. The sum of the interior angles of a triangle is always 180º and an obtuse angle is larger than 90º. Thus the sum of two obtuse angles would be greater than 180º even without including an acute angle.

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.

An obtuse triangle has 1 obtuse angle and 2 acute angles

A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles

It is an obtuse triangle having 1 obtuse angle and 2 different acute angles Or it is an isosceles triangle having 1 obtuse angle and 2 equal acute angles

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.

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)

Yes. A triangle can have only one obtuse angle. The other two angles will always be acute.

Angles: acute angle, obtuse angle, right angle Triangles: isosoles triangle, scalene triangle, equadrital triangle, right triangle, acute triangle, obtuse triangle

A triangle has at two acute angles and the third angle is either an acute angle, a right angle or an obtuse angle.

Yes. Every triangle with an obtuse angle must have two acute angles.

That would be an obtuse triangle.

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.
