The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared.
pythagorean theorem calc: find a, b=n/a, c=n/a
Pythagorean Theorem Calculator
a^2 + b^2 = c^2
Solving for a
a^2 = c^2 - b^2
b – leg
c – hypotenuse
make sure
c>a
c = 6; b = 5;
