All of the angles in a triangle must add up to exactly 180 degrees. 89, 90, and 91 degrees equal up to 270 degrees. So these angles are not characteristics of a triangle.
A right triangle is a triangle that contains a 90 degree angle, an obtuse triangle contains an angle that is from 91 degrees to 179 degrees.
The measure can be anywhere from 91 degrees to 179 degrees. 90 degrees is a right angle and 180 degrees is a straight line.
2 of the angles in a triangle are 32 and 91 degrees. What is the 3rd angle?
equiangular triangle
An obtuse angled triangle.

There are three angles in a triangle that amount to 180 degrees. If one of these angles was 91 degrees (an obtuse angle) then the sum of the other two angles must be 89 degrees.
equiangular triangle
An acute angled scalene triangle.
It is an isosceles triangle
An obtuse triangle.
Obtuse.
No, an obtuse triangle can not have more than one obtuse angle. This is because all of the angles have to add up to 180 and the smallest obtuse angle you can have is 91 degrees. So 180-91=89. 89 degrees is the angle that you need to complete the triangle and it is an acute angle. Therefore, you can not have more than one obtuse angle in an obtuse triangle.
