If the 2 acute angles are equal then it is an isosceles triangle otherwise it is a scalene triangle.
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.
A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.
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.
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 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.
Yes. A triangle can have only one obtuse angle. The other two angles will always be acute.
No
a trapezoid :) * * * * * Not necessarily. A trapezoid can have two right angles, one acute and one obtuse angle. A parallelogram which is not a rectangle must have 2 acute and 2 obtuse angles.
A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.
One angle must be an obtuse angle and the other two angles must be acute angles
It can be called obtuse, scalene ( if two acute angles are different ), or isosceles ( if two acute angles are the same ).
An obtuse triangle
