About Right Triangle Calculator

Specialized right-angled triangle solver that computes the hypotenuse from two legs using c = sqrt(a^2 + b^2).

What is Right Triangle Calculator?

Specialized right-angled triangle solver that computes the hypotenuse from two legs using c = sqrt(a^2 + b^2).

How to Use This Calculator

  1. Enter base leg a and height leg b.
  2. View hypotenuse, acute angles, and triangular area.

The Mathematical Formula & Variables

c = sqrt(a^2 + b^2); Area = (a * b) / 2

Step-by-Step Worked Example

Scenario: Right triangle with legs 3 and 4.

  1. c = sqrt(3^2 + 4^2) = sqrt(9 + 16) = sqrt(25) = 5.
  2. Area = (3 * 4) / 2 = 6.

Result: Hypotenuse = 5, Area = 6
