Determining the Type of Triangle Using Python

In this project, we will discuss a Python code snippet that determines the type of triangle based on its side lengths. We'll explain each step of the code and provide the final working code at the end.

Getting User Input

To begin, we need to obtain the lengths of the three sides of the triangle from the user. We can use the input() function to prompt the user to enter the values. Let's store the user's input in variables called a, b, and c:

a = float(input("Enter the length of the first side: "))
b = float(input("Enter the length of the second side: "))
c = float(input("Enter the length of the third side: "))

Checking the Type of Triangle

Next, we will use a series of if and elif statements to check the type of triangle based on its side lengths.

if a == b == c:
    print("The triangle is equilateral.")
elif (a <= 0) or (b <= 0) or (c <= 0):
    print("The triangle is not possible.")
elif a == b or b == c or c == a:
    print("The triangle is isosceles.")
else:
    print("The triangle is scalene.")

In this code snippet, we check the following conditions:

• If all three sides are equal (a == b == c), the triangle is equilateral.
• If any side is less than or equal to zero (a <= 0 or b <= 0 or c <= 0), the triangle is not possible.
• If any two sides are equal (a == b or b == c or c == a), the triangle is isosceles.
• If none of the above conditions are met, the triangle is scalene.

We print the corresponding message based on the type of triangle identified.

Final Code

Here's the complete Python code that determines the type of triangle based on its side lengths:

a = float(input("Enter the length of the first side: "))
b = float(input("Enter the length of the second side: "))
c = float(input("Enter the length of the third side: "))

if a == b == c:
    print("The triangle is equilateral.")
elif (a <= 0) or (b <= 0) or (c <= 0):
    print("The triangle is not possible.")
elif a == b or b == c or c == a:
    print("The triangle is isosceles.")
else:
    print("The triangle is scalene.")

That's it! You now have a Python code snippet that determines the type of triangle based on its side lengths. Feel free to modify the code or use it as a starting point for your own projects. Happy coding!
