no you can have an obtuse scalene triangle

No because an equilateral triangle has 3 equal acute angles of 60 degrees but a scalene triangle has 3 acute angles of different sizes.

equilateral triangle, acute triangle, some isosceles and scalene triangles

Scalene triangles are polygons like all triangles. The lengths of the sides of scalene triangle are all different.

No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.

No, not necessarily.

yes all scalene triangles are actue. All the angles are 60 degrees. :)

No. Scalene triangles have no equal sides or angles but can be obtuse, right angled or acute.

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.

Scalene triangles those triangles in which all the sides are of different lengths, but in isosceles triangles two sides of the triangle are equal in length. Therefore, no scalene triangle can ever be isosceles.
