Right Triangle Validator

Write a Python program to check whether three given lengths (integers) of three sides form a right triangle. Print "Yes" if the given sides form a right triangle otherwise print "No".

Input:
Integers separated by a single space.
1 ≤ length of the side ≤ 1,000

Visual Presentation:

Sample Solution:

Python Code:

# Print statement to prompt the user to input three integers representing sides of a triangle
print("Input three integers (sides of a triangle)")

# Using map and split to take three space-separated integers as input, then converting them to a list of integers
int_num = list(map(int, input().split()))

# Sorting the list of integers to assign variables x, y, and z with the values of the sorted sides
x, y, z = sorted(int_num)

# Checking if the given sides form a Pythagorean triple (right-angled triangle)
if x**2 + y**2 == z**2:
    print('Yes')  # Print 'Yes' if the condition is met
else:
    print('No')   # Print 'No' if the condition is not met

Sample Output:

Input three integers(sides of a triangle)
 8 6 7
No

Explanation:

Here is the breakdown of the above Python exercise:

• Prints a prompt asking the user to input three integers representing triangle sides.
• Takes the input as three space-separated integers, converts them to a list of integers.
• Sorts the list by assigning variables x, y, and z with the values of the sorted sides.
• Check whether the sorted sides form a Pythagorean triple (right-angled triangle) using the Pythagorean theorem.
• Prints 'Yes' if the sides satisfy the Pythagorean theorem, otherwise prints 'No'.
