Pythagorean Theorem Calculator Information
What is the Pythagorean Theorem?
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides:
- a = One leg
- b = Other leg
- c = Hypotenuse
Example: a = 3, b = 4
c = 5
Why Use the Pythagorean Theorem?
- Geometry: Find missing sides in right triangles
- Construction: Ensure corners are square and layouts are accurate
- Navigation: Calculate straight-line distances
- Everyday Life: Solve problems involving ladders, ramps, and more
Tips for Accurate Calculation
- Use Consistent Units: All sides must be in the same unit (e.g., cm, in, m)
- Check for Right Angle: The theorem only applies to right triangles
- Double-Check Inputs: Enter values carefully to avoid errors
Frequently Asked Questions (FAQ)
A: The hypotenuse is the longest side of a right triangle, opposite the right angle.
A: No, the Pythagorean theorem only applies to right triangles.
A: Yes! Enter your values in any unit (cm, in, m, ft, etc.) and the result will be in the same unit.
A: The calculator works with decimals and whole numbers.
A: Use the Law of Cosines for non-right triangles.
