C program to check if the triangle is equilateral, isosceles or scalene triangle

In the realm of geometry, classifying triangles based on their side lengths is essential. In this article, we'll explore how to create a simple C program that checks whether a triangle is equilateral, isosceles, or scalene.

Understanding Triangle Classification

• Equilateral Triangle: All three sides of an equilateral triangle are of equal length.
• Isosceles Triangle: An isosceles triangle has two sides of equal length.
• Scalene Triangle: A scalene triangle has no sides of equal length.

C program to check if the triangle is equilateral, isosceles or scalene triangle

Let's delve into the C programming language to create a program that classifies a triangle based on its side lengths.

#include <stdio.h>

int main() {
    float side1, side2, side3;

    // Input from the user
    printf("Enter three sides of the triangle: ");
    scanf("%f %f %f", &side1, &side2, &side3);

    // Checking triangle classification
    if (side1 == side2 && side2 == side3) {
        printf("The triangle is an Equilateral Triangle.");
    } else if (side1 == side2 || side1 == side3 || side2 == side3) {
        printf("The triangle is an Isosceles Triangle.");
    } else {
        printf("The triangle is a Scalene Triangle.");
    }

    return 0;
}

Output

Enter three sides of the triangle: 10 10 10
The triangle is an Equilateral Triangle.

Triangle Classification: The program compares the side lengths to determine the type of triangle based on equality between sides.

In this article, we've created a simple C program that efficiently classifies a triangle based on its side lengths. Understanding the concepts of equilateral, isosceles, and scalene triangles through C programming allows us to identify different types of triangles accurately.
