What is a scalene triangle?

A scalene triangle is a triangle that comprises three unequal sides. To put it simply, all of its sides have completely different lengths.

The scalene triangle calculator on your left allows you to calculate the area of a scalene triangle, as well as its perimeter, sides, heights and angles!

💡 Take a look at the triangle area calculator and the perimeter of a triangle calculator to find out more!

How do I calculate the perimeter of a scalene triangle?

Calculating the perimeter of a scalene triangle is extremely simple!

  1. Follow the formula:

    Perimeter = a + b + c

    where:

    • a,b, andcare sides of the scalene triangle.
  2. Enjoy the results – you’ve finished the easiest part of scalene triangle calculations! 🎉

How to calculate the area of a scalene triangle?

We may use multiple equations – the area of a scalene triangle is calculated in exactly the same way as for all the triangles.

Let’s choose the equation that suits you best:

  • Area = 0.5 × Base × Height
  • Area = 0.5 × a × b × sin(γ)
  • Area = 0.25 × √((a + b + c) × (-a + b + c) × (a - b + c) × (a + b - c))
  • Area = a² × sin(β) × sin(γ)/ (2 × sin(β + γ))

How to calculate a scalene triangle’s height?

There are a few scalene triangle equations that may be of help:

  • Calculate height for any triangle:

    Height = 2 × Area/ Base

    Height = 0.5 × √((a + b + c) × (-a + b + c) × (a – b + c) × (a + b – c)) / b

  • For the right triangle:

    Heightᶜ = a × b / c

    where:

    • a, b, and c are sides of the triangle; and

    • Heightᶜ is the height of a base c.

How to calculate the area of a scalene right triangle?

The formula for the area of a scalene right triangle is just the same as for any other right triangle:

Area = a × b / 2

or

Area = b × √(c² - b²) / 2

where:

  • aandbare the perpendicular sides; and
  • cis the hypotenuse.
