Yes, normally it is but it can also be an isosceles triangle if it has an obtuse angle and 2 equal acute angles.

Some obtuse triangles are scalene?
Obtuse triangles can also be scalene if none of the sides are of equal length. Otherwise, it is an isosceles triangle.
Are scalene triangles all obtuse?
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.
What are the four types of triangles?
right obtuse acute and scalene
What is three types of triangles?
They are: right angle, isosceles and equilateral triangles There are also scalene and obtuse triangles
Can scalene triangles be acute or obtuse?
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.
What are some triangles?
isocles, equilateral, obtuse, acute, scalene, right
What traingle don't have a right angle?
Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
Are the exterior angles of a scalene triangle always obtuse?
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.
What are the kinds of triangles according to measure of their sides and angles?
They are: equilateral, isosceles, obtuse, scalene and right angle triangles
How do you classify triangles in two different ways?
Triangles are classed as: scalene, right angle, obtuse, isosceles and equilateral
Are all scalene triangles acute triangles?
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.
What triangles is impossible to draw right obtuse triangle right scalene triangle acute isosceles triangles or a obtuse scalene triangle?
A triangle can only have 1 right angle or 1 obtuse angle in it because its 3 interior angles add up to 180 degrees
