SCALENE TRIANGLE

__SCALENE TRIANGLE -__

**A scalene triangle is a type of triangle in which all three sides have different lengths, and consequently, all three interior angles are also different. Here are the key properties of a scalene triangle:**

__Unequal sides:-__No two sides are of the same length.__Unequal angles:-__All three angles are different, though they still sum up to 180° (as with any triangle).__No symmetry:-__Unlike isosceles or equilateral triangles, scalene triangles do not have any lines of symmetry.__Height and area:-__There is no simple formula for height, but the area A can be calculated using Heron's formula, given the lengths of the sides a, b, and c:

** a + b + c**

** s = ------------ (semi-perimeter)**

** 2**

** A = √s (s−a) (s−b) (s−c)**

**Scalene triangles can be acute, right, or obtuse, depending on the nature of their angles.**
