Obtuse triangles can also be scalene if none of the sides are of equal length. Otherwise, it is an isosceles triangle.

No, a scalene triangle is simply a triangle where all angles are not equal and all side lengths are not equal, therefore they can or cannot be obtuse.
A scalene triangle can have 1 obtuse angle and 2 different acute angles or it can have 3 different acute angles providing that the 3 angles in both scalene triangles add up to 180 degrees.
No, scalene triangles can be obtuse, right or acute triangles. A 3 - 4 -5 right triangle (lengths of the sides) is one example of a right-scalene triangle. In fact, with the exception of the [45°, 45°, 90°] right triangle (which is isosceles) all other right triangles are scalene.
Acute, equilateral, isosceles, obtuse, right angle and scalene.
A 115 degree angle is classified as obtuse. Scalene and isosceles refer to types of triangles.
