Area:

This tool focuses on two essential triangle calculations:

  • Pythagorean Theorem – to find the hypotenuse of a right triangle
  • Triangle Area Calculation – using all three sides

Instead of memorizing formulas or performing complex calculations, you can enter values and get instant, accurate results.

How the Sides of Triangle Calculator Works

This calculator is divided into two main sections:

1. Pythagorean Calculation

Used to calculate the hypotenuse of a right triangle when you know the other two sides.

It follows the formula:

c2=a2+b2c^2 = a^2 + b^2c2=a2+b2

bbb

c=a2+b2≈21.21c = \sqrt{a^2 + b^2} \approx 21.21c=a2+b2​≈21.21

a2+b2=c2≈225.00+225.00=450.00a^2 + b^2 = c^2 \approx 225.00 + 225.00 = 450.00a2+b2=c2≈225.00+225.00=450.00abc

2. Area Calculation

Used to calculate the area of any triangle using all three sides.

It applies Heron’s Formula:

A=s(s−a)(s−b)(s−c)A = \sqrt{s(s-a)(s-b)(s-c)}A=s(s−a)(s−b)(s−c)​

Where:

  • s=a+b+c2s = \frac{a + b + c}{2}s=2a+b+c​ (semi-perimeter)

Practical Examples

✅ Example 1: Finding Hypotenuse

Imagine you're measuring a ladder placed against a wall:

  • Side A (height) = 6 meters
  • Side B (base) = 8 meters

Result:

  • Hypotenuse = 10 meters

This helps determine the exact ladder length required.

✅ Example 2: Calculating Area of Land

Suppose you have a triangular plot of land:

  • Side A = 5 meters
  • Side B = 6 meters
  • Side C = 7 meters

Result:

  • Area ≈ 14.70 square meters

This is useful for land measurement or construction planning.
