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

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.

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.

Acute, equilateral, isosceles, obtuse, right angle and scalene.

Acute, equilateral, isosceles, obtuse, right angle, scalene are all names of different types of triangles.

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

They are: right angle, isosceles and equilateral triangles There are also scalene and obtuse triangles

Thay aren't. A scalene triangle has 3 uncongruent sides. While an isoceles has only one uncongruent.

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.
