How to use the MathCalc Pythagorean theorem calculator?

Step by step:

  • Select the “Find side” from Find hypotenuse, find side A, and Find side B.
  • If you choose to find the hypotenuse, then enter Side A and Side B.
  • If you choose to find side A, then enter side B and hypotenuse C.
  • If you choose to find side B, then enter side A and hypotenuse C.
  • After entering the values, click on calculate, and in seconds, you will see the result.

Example 1: If we choose to find the hypotenuse.

Enter 3 in the “side A” box and 4 in the “side B” box.

Step by step:

  • Pythagorean theorem: c² = a² + b²
  • Given: a = 3, b = 4
  • Calculation: c² = 3² + 4² = 9 + 16 = 25
  • Therefore, c = √25 = 5

result:

  • Hypotenuse (c) = 5

Example 2: If we choose to find side A.

Enter 6 in the side B box and 10 in hypotenuse C.

Step by step:

  • The Pythagorean theorem rearranged: a² = c² - b²
  • Given: b = 6, c = 10
  • Calculation: a² = 10² - 6² = 100 - 36 = 64
  • Therefore, a = √64 = 8

result:

  • Side A = 8

Example 3: If we choose to find side B

Enter 5 in the side A box and 13 in the hypotenuse box.

Step by step:

  • The Pythagorean theorem rearranged: b² = c² - a²
  • Given: a = 5, c = 13
  • Calculation: b² = 13² - 5² = 169 - 25 = 144
  • Therefore, b = √144 = 12

result:

  • Side B = 12
