A
Sum of interior angles in a tringle = 180∘.
An obtuse angle measures more than 90 degrees but less than 180 degrees.
A triangle can have only one obtuse angle because if there were two obtuse angles, then the sum of two obtuse angles would always be greater than 180∘.
Hence, a triangle can have only one obtuse angle.
