Pythagorean Theorem Calculator

Solve for sides of a right triangle.

Pythagorean Theorem

a² + b² = c² (for right triangles)

A Pythagorean theorem calculator is the quickest way to solve right-triangle problems without manual algebra.

Whether you're a student checking homework or a DIYer measuring a corner, this tool turns the classic relationship between the sides of a right triangle into instant answers. Discover the tool’s purpose, how to operate it, and which related calculators make geometry simpler.

How a² + b² Explains Right Triangle Geometry

This rule means the hypotenuse’s squared length equals the combined squares of the triangle’s other two sides. Written several ways, most commonly as "a²+b²=c²" or in words as "a squared plus b squared equals c squared," this formula is the backbone of many geometry tasks. Enter values for legs a and b into the calculator, and you’ll get c in seconds.

Hypotenuse Calculator & Triangle Calculator

  • Find the missing side when two sides are known, a perfect job for a hypotenuse calculator.
  • Convert measurements for construction or mapping tasks using an easy Triangle Calculator interface.

These bullet points show how the tool saves time and reduces calculation errors when accuracy matters.

Best Calculators & Apps for Geometry Tasks

A general math calculator helps with unit conversion and arithmetic steps you might need before or after using the pythagorean tool.

When problems involve arcs or chord lengths, the circle calculator complements triangle work by converting radii and angles into linear measures. Also, look for a Pythagorean theorem calculator app if you need on-the-go results from your phone or tablet.

Pythagorean Theorem: Formula, Proof, and Worked Problems

If you prefer formulas, the Pythagorean theorem formula shows the same idea in symbolic form. The phrase "a squared plus b squared" appears often in textbooks; the calculator implements that step and applies the square root automatically. For angle-specific tasks, the Pythagorean Theorem calculator angle mode can help you relate side lengths to trigonometric values, while specialized entries like Pythagoras' Theorem hypotenuse formula remind you how the pieces fit together.

FAQs

  1. How do I calculate the hypotenuse using the theorem? Use the hypotenuse calculator or input the two leg values into the Pythagorean theorem calculator to compute c via the square root of (a² + b²). This gives a precise result every time.
  2. Can I use this for non-right triangles? The formula and related tools are for right triangles only. For other triangles, use trigonometry or law-of-cosines calculators rather than a standard Triangle Calculator.
  3. Is there a mobile app that shows steps? Yes, search for a Pythagorean theorem calculator app that displays both the a squared plus b squared step and the square root operation so you can learn the process as you calculate.
  4. What if I want the calculation shown as a²+b²=c²? Choose an option labeled “a2+b2=c2 calculator” or enable “show steps” in the Pythagorean calculator; many tools provide the symbolic representation and the final numeric result.
