# Python Math: Create a Pythagorean theorem calculator

## Python Math: Exercise-68 with Solution

Write a Python program to create a Pythagorean theorem calculator.

Note : In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

**Sample Solution**:

**Python Code:**

```
from math import sqrt
print('Pythagorean theorem calculator! Calculate your triangle sides.')
print('Assume the sides are a, b, c and c is the hypotenuse (the side opposite the right angle')
formula = input('Which side (a, b, c) do you wish to calculate? side> ')
if formula == 'c':
side_a = int(input('Input the length of side a: '))
side_b = int(input('Input the length of side b: '))
side_c = sqrt(side_a * side_a + side_b * side_b)
print('The length of side c is: ' )
print(side_c)
elif formula == 'a':
side_b = int(input('Input the length of side b: '))
side_c = int(input('Input the length of side c: '))
side_a = sqrt((side_c * side_c) - (side_b * side_b))
print('The length of side a is' )
print(side_a)
elif formula == 'b':
side_a = int(input('Input the length of side a: '))
side_b = int(input('Input the length of side c: '))
side_c = sqrt(side_c * side_c - side_a * side_a)
print('The length of side b is')
print(side_c)
else:
print('Please select a side between a, b, c')
```

Sample Output:

Pythagorean theorem calculator! Calculate your triangle sides. Assume the sides are a, b, c and c is the hypotenuse (the side opposite the right angle Which side (a, b, c) do you wish to calculate? side>a Input the length of side b:10 Input the length of side c:15 The length of side a is 11.180339887498949
