The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared.

### Pythagorean Theorem Calculator

`a^2 + b^2 = c^2`

**Solving for b**

`b^2 = c^2 - a^2`

a - leg c - hypotenuse

make sure

`c`

>`a`

`c = 3; a = 2;`

## Python Pythagorean Theorem

`from math import sqrt D = "Which side are you looking for? " # c**2 = b**2 + a**2 while True: print(f"\n{D}") x = input("[a, b, c, exit]: ") #a if x.lower() == "a": f = input("Give me (b) and (c): ") b, c = f.split(' ') a = sqrt((int(c)**2) - (int(b)**2)) print("\nSide (a) is equal to %.2f" % (a)) #b elif x.lower() == "b": f = input("Give me (a) and (c): ") a, c = f.split(' ') b = sqrt((int(c)**2) - (int(a)**2)) print("\nSide (b) is equal to %.2f" % (b)) #c elif x.lower() == "c": f = input("Give me (a) and (b): ") a, b = f.split(' ') c = sqrt((int(a)**2) + (int(b)**2)) print("\nSide (b) is equal to %.2f" % (c)) elif x.lower() == "exit": print("=======================================================================") s = input("Do you want to exit?[y, n]: ") if s.lower() == "y": break elif s.lower() == "n": continue`

`Which side are you looking for? [a, b, c, exit]: a Give me (b) and (c): 3 4 Side (a) is equal to 2.65`
