How does the Pythagorean Theorem Calculator work?
Free Pythagorean Theorem Calculator - Figures out based on user entry the missing side or missing hypotenuse of a right triangle. In addition, the calculator shows the proof of the Pythagorean Theorem and then determines by numerical evaluation if the 2 sides and hypotenuse you entered are a right triangle using the Pythagorean Theorem
This calculator has 3 inputs.

What 3 formulas are used for the Pythagorean Theorem Calculator?

What 5 concepts are covered in the Pythagorean Theorem Calculator?
length
the measurement or extent of something from end to end
pythagorean theorem
a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides
a2 + b2 = c2
side
line segment joining two vertices in a polygon also known as an edge
theorem
A statement provable using logic
triangle
a flat geometric figure that has three sides and three angles
Example calculations for the Pythagorean Theorem Calculator
  1. a=3,b=4
  2. a=3,c=5
  3. b=4,c=5
  4. find the hypotenuse of a right triangle that has legs of 4 inches and 5 inches
  5. 3^2 + 4^2 = c^2
  6. 3^2 + b^2 = 5^2
  7. a^2 + 4^2 = 5^2
