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.


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 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.


All kinds of triangles?

They are classified as: scalene, obtuse, right angle. equilateral and isosceles


Are all scalene triangles also acute triangles?

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


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


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.


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.

Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles


Does all angles of a scalene triangles are acute angles?

Not always because one of the interior angles could be obtuse.
