Python: Get the third side of right angled triangle from two given sides

Sample Solution:

Python Code:

# Define a function 'pythagoras' that calculates the missing side of a right-angled triangle.
def pythagoras(opposite_side, adjacent_side, hypotenuse):
    # Check if the opposite side is marked as unknown.
    if opposite_side == str("x"):
        return ("Opposite = " + str(((hypotenuse**2) - (adjacent_side**2))**0.5))
    # Check if the adjacent side is marked as unknown.
    elif adjacent_side == str("x"):
        return ("Adjacent = " + str(((hypotenuse**2) - (opposite_side**2))**0.5))
    # Check if the hypotenuse is marked as unknown.
    elif hypotenuse == str("x"):
        return ("Hypotenuse = " + str(((opposite_side**2) + (adjacent_side**2))**0.5))
    else:
        return "You know the answer!"  # Return this message if all sides are known.

# Test the function with different inputs and print the results.
print(pythagoras(3, 4, 'x'))
print(pythagoras(3, 'x', 5))
print(pythagoras('x', 4, 5))
print(pythagoras(3, 4, 5))

Sample Output:

Hypotenuse = 5.0
Adjacent = 4.0
Opposite = 3.0
You know the answer!

Explanation:

The above Python code defines a function called "pythagoras()" that calculates the missing side of a right-angled triangle using the Pythagorean theorem. Here's a brief explanation:

  • The function takes three arguments: 'opposite_side', 'adjacent_side', and 'hypotenuse'. One of these sides is marked as 'x', indicating it is unknown and needs to be calculated.
  • The function uses conditional statements to check which side is marked as 'x' and calculates its value based on the Pythagorean theorem.
  • If the opposite side is marked as 'x', it calculates and returns the value of the opposite side using the theorem.
  • If the adjacent side is marked as 'x', it calculates and returns the value of the adjacent side.
  • If the hypotenuse is marked as 'x', it calculates and returns the value of the hypotenuse.
  • If none of the sides is marked as 'x', it returns the message "You know the answer!" since all sides are known.
  • The code then tests the "pythagoras()" function with different inputs, representing various scenarios of known and unknown sides, and prints the results.
