What triangle has a 120 degree angle 35 degree angle and a 25 degree angle?

When a triangle has no angles =to 90 degrees, it is called an oblique triangle.

When one of the angles of an oblique triangle is greater than 90 degrees, it can also be called an obtuse triangle.

Technically, the triangle described would also be a type of scalene triangle, although we should only call it this when it is defined by the length of its sides, rather than by its internal angles.
