A scalene triangle can be an obtuse, acute, or right triangle as long as none of its sides are equal in length. An equiangular triangle is a kind of acute triangle, and is always equilateral. Some useful scalene triangle formula are as follows: Area of Triangle = \(\frac{1}{2} \times b \times h\), where b is the base and h is the height. Note: It is possible for an obtuse triangle to also be scalene or isosceles. In geometry, Scalene Triangle is a triangle that has all its sides of different lengths. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees. An obtuse triangle is one where one of the angles is greater than 90 degrees.
