Lets first understand, what is a scalene triangle and how we can find different properties of a scalene triangle?

Triangle

A triangle is a polygon with three edges and three vertices. Triangle is one of the basic shapes in geometry.

Any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

A scalene triangle has all its sides of different lengths. Equivalently, it has all angles of different measure.

Formulas

Let the three sides of the Scalene Triangle be \(a\), \(b\) and \(c\) units.

Semi-perimeter (s) of the Scalene Triangle will be \(\dfrac{1}{2}(a+b+c)\) units.

Perimeter (P) of the Scalene Triangle will be \((a+b+c)\) units.

Area of the Scalene Triangle is given by

$$A=\sqrt{s(s-a)(s-b)(s-c)}\hspace{0.2cm}square\hspace{0.1cm}units,$$where \(s=\dfrac{(a+b+c)}{2}\).

Inradius (r) of the Scalene Triangle will be \(\left(\dfrac{A}{s}\right)\) units.

Circum-radius (R) of the Scalene Triangle will be \(\left(\dfrac{abc}{4A}\right)\) units.

For calculating different properties of the scalene triangle using above scalene triangle calculator, you have to just write the values in the given input boxes and press the calculate button, you will get the result.
