Pythagorean Theorem Calculator
Calculate the missing side length of a right triangle using the Pythagorean Theorem formula: a² + b² = c². Enter any two side lengths to find the third.
Understanding the Pythagorean Theorem
What is the Pythagorean Theorem?
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) equals the sum of squares of the other two sides (a and b). This relationship is expressed as: a² + b² = c².
Key Features:
- Only works for right triangles (triangles with one 90-degree angle)
- The hypotenuse is always the longest side
- Can be used to find any side if you know the other two
- Essential in geometry, engineering, and architecture
Common Applications
- Construction and building design
- Navigation and distance calculations
- Engineering and structural analysis
- Computer graphics and game development
