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. Since the lengths of sides are unequal and even angles are of different measures, a scalene triangle doesn't show symmetry.įAQs on Scalene Triangle What is a Scalene Triangle in Geometry?Ī scalene triangle is a triangle in which all three sides are of different lengths.It also follows the angle sum property of the triangle.A scalene triangle has three sides, each of a different length and three angles each of different measurements.Here, 's' is the semi perimeter of a triangle which is, s = (a b c)/2, and a, b, and c denotes the sides of the triangle. Thus, Area of the scalene triangle, \(\begin\) square units. Now, if the height and base are not given, but the sides of the triangle are known, then we apply Heron’s formula. “h” refers to the height of the triangle.The area of a triangle =(1/2) × b × h square units. Thus, the perimeter of the scalene triangle = (a b c) units, where a, b, and c denote all three sides of the scalene triangle. The perimeter of a triangle = sum of all the three sides of the triangle = (a b c) units. There are two main formulas of a scalene triangle which are related to the Perimeter of a Scalene Triangle and the area of a scalene triangle.
