no you can have an obtuse scalene triangle

No

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.

Yes.

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

scalene triangles can be the same as acute triangles beacause scalene triangles are triangles with 3 different angles and sides. An acote triangle needs to have 3 angles less than 90 degrees.

equilateral triangle, acute triangle, some isosceles and scalene triangles

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.
