A triangle with one angle measuring 91 degrees is classified as an obtuse triangle. In obtuse triangles, one angle is greater than 90 degrees, while the other two angles are acute (less than 90 degrees). Thus, the triangle's specific name would simply be an obtuse triangle.
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.

2 of the angles in a triangle are 32 and 91 degrees. What is the 3rd angle?
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.
An obtuse triangle.
It is an isosceles triangle
Obtuse.
