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.
Acute, equilateral, isosceles, obtuse, right angle and scalene.
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.
It can be any one of the triangles in the list.
Obtuse triangles can also be scalene if none of the sides are of equal length. Otherwise, it is an isosceles triangle.
