The perimeter of a scalene triangle can be calculated using the formula, Perimeter of scalene triangle = sum of all sides, that is, Perimeter = a + b + c, where a, b, c are the 3 sides of the triangle. How to Find the Perimeter of a Scalene Triangle? In an obtuse scalene triangle, one of the interior angles is more than 90° and the other 2 angles are less than 90°. Yes, scalene triangles can be obtuse triangles.

☛Check more formulas related to triangles: When the base and height of the triangle are given, then we apply the following formula: Area of triangle = (1/2) × base × height. Here, a, b and c are the 3 different sides of the scalene triangle, and 's' is the semi perimeter of the triangle. The area of a scalene triangle can be calculated using Heron's formula, Area of triangle = √, when all the three side lengths are given. How to Find the Area of a Scalene Triangle? So, the value of c will be the length of the missing side, that is, c = 8 units. Let us substitute the given values in the formula, Perimeter of triangle = a + b + c. The perimeter of a scalene triangle = a + b + c, where a, b and c are the 3 sides. For example, if the perimeter of a scalene triangle is 24 units, and two of its sides are 10 units and 6 units, the missing side can be calculated as follows. We can use the formula for the perimeter and substitute the given values to know the length of the missing side. We can find the missing side of a scalene triangle if the perimeter and the other 2 sides are given.

Scalene triangles are triangles with sides of different lengths. How to Find the Missing Side Length of a Scalene Triangle? In an isosceles triangle, two out of the three sides are of the same length and the angles opposite to equal sides are of equal measure. In a scalene triangle, none of the sides are of the same length and none of the angles are of equal measure. What is the Difference Between an Isosceles Triangle and a Scalene Triangle? Since the sides of the triangle are of unequal lengths, even the 3 angles are of different measures.
