Area Triangle

Calculate sides, perimeter, and area of a triangle.

The Math Behind

The app uses geometry principles to make precise calculations.

1. Sides and Perimeter Calculation

   The perimeter of a triangle is simply the sum of its three side lengths. If you know the lengths of all sides, the formula is:

   $\text{Perimeter} = a + b + c$

   Where a, b, and c represent the three side lengths of the triangle.

2. Area Calculation Using Base and Height

   If the height of the triangle is known, you can use this formula for area:

   $\text{Area} = \frac{1}{2} \times \text{Base} \times \text{Height}$

The app handles all this math for you—just input a combination of base, height and diagonal, and you’ll get instant results.
