Question

Write a program that accepts the lengths of three sides of a triangle as inputs. The program output should indicate whether or not the triangle is a right triangle.

Recall from the Pythagorean theorem that in a right triangle, the square of one side equals the sum of the squares of the other two sides.

• Use The triangle is a right triangle. and The triangle is not a right triangle. as your final outputs.

An example of the program input and proper output format is shown below:

Enter the first side: 3
Enter the second side: 4
Enter the third side: 5

The triangle is a right triangle

Answer 1

Explanation:

Here is the code which takes three sides of a triangle

Then it tries to find in all the three combinations possible, if there are any pythagorean triplet.

if yes, it prints that the triangle is a right angled triangle.

Code:

first = float(input("Enter first side: "))
second = float(input("Enter second side: "))
third = float(input("Enter third side: "))

if ((first**2) == (second**2 + third**2)) or ((second**2) == (first**2 + third**2)) or ((third**2) == (second**2 + first**2)):
print("The triangle is a right triangle")
else:
print("The triangle is not a right triangle")

Output:
