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