Pythagorean Theorem
Calculate the hypotenuse of a right-angled triangle.
c² = a² + b²
Formula Explanation
The square of the hypotenuse equals the sum of the squares of the other two sides.
Variables Explained
a and b = perpendicular sides; c = hypotenuse.
Solved Example
Find the hypotenuse when the perpendicular sides are 3 cm and 4 cm.
c = √(9 + 16) = 5 cm.
