Formula Used:

The Pythagorean Theorem is given by:

\[ a^2 + b^2 = c^2 \]

Where:

  • a: Length of one leg
  • b: Length of the other leg
  • c: Length of the hypotenuse

To calculate:

  • Hypotenuse (\( c \)): \( c = \sqrt{a^2 + b^2} \)
  • Side A (\( a \)): \( a = \sqrt{c^2 - b^2} \)
  • Side B (\( b \)): \( b = \sqrt{c^2 - a^2} \)

For example, if \( a = 3 \) and \( b = 4 \), then \( c = \sqrt{3^2 + 4^2} = \sqrt{9 + 16} = \sqrt{25} = 5 \) units.
