Triangle Leg Calculator

Solving right triangles is a fundamental task in mathematics, physics, and engineering. Whether you’re a student, teacher, or professional, manually calculating a missing leg can be time-consuming and prone to error. The Triangle Leg Calculator simplifies this process by instantly computing the missing side of a right triangle when the hypotenuse and one leg are known.

📐 Triangle Leg Calculator

Please enter valid numbers. Hypotenuse must be larger than leg.

Result

Missing Leg:

Using the Pythagorean theorem c2=a2+b2c^2 = a^2 + b^2c2=a2+b2, this tool provides fast and accurate results, helping you solve geometry problems efficiently and improving your understanding of triangular relationships.

How to Use the Triangle Leg Calculator

The tool is designed for simplicity. Follow these steps:

  1. Enter the Hypotenuse (c):
    Input the length of the hypotenuse, the longest side of the right triangle.
  2. Enter the Other Leg (a or b):
    Provide the length of the known leg. The calculator will determine the missing leg automatically.
  3. Click “Calculate”:
    Press the Calculate button to instantly display the missing leg of the triangle.
  4. Optional Actions:
    • Reset: Clears all fields to start a new calculation.
    • Copy Results: Copy the missing leg value to your clipboard.
    • Share: Share the result directly via supported platforms.
  5. Check for Errors:
    If the hypotenuse is smaller than or equal to the entered leg, the calculator will display an error message. Always ensure the hypotenuse is the largest side.

Practical Examples of Triangle Leg Calculations

Example 1: Simple Right Triangle

  • Hypotenuse (c): 10
  • Known Leg (a): 6

Calculation:b=c2−a2=102−62=100−36=64=8b = \sqrt{c^2 – a^2} = \sqrt{10^2 – 6^2} = \sqrt{100 – 36} = \sqrt{64} = 8b=c2−a2​=102−62​=100−36​=64​=8

Result: The missing leg (b) is 8 units.

Example 2: Engineering Application

  • Hypotenuse (c): 15
  • Known Leg (b): 9

Calculation:a=c2−b2=225−81=144=12a = \sqrt{c^2 – b^2} = \sqrt{225 – 81} = \sqrt{144} = 12a=c2−b2​=225−81​=144​=12

Result: The missing leg (a) is 12 units, which is useful in construction or structural design calculations.
