C Program to Check Triangle is Equilateral Isosceles or Scalene

by suresh

Write a C Program to Check Triangle is Equilateral Isosceles or Scalene with example. For example, a, b, and c are sides of a triangle

  • Equilateral Triangle: If all sides of a triangle are equal, then it is an Equilateral triangle. a= b = c
  • Isosceles Triangle: If any of the two sides are equal, it is an Isosceles Triangle. a= b or a= c or b = c
  • Scalene Triangle: If none of the sides are equal, it is a Scalene Triangle. a != b != c

C Program to Check Triangle is Equilateral Isosceles or Scalene Example

This program helps the user to enter all sides of a triangle. And then C Programming find whether it is an Equilateral Triangle, Isosceles Triangle, or Scalene Triangle using Else If.

/* C Program to Check Triangle is Equilateral Isosceles or Scalene */

#include<stdio.h>
 
int main()
{
	int side1, side2, side3;
 
  	printf("\n Please Enter Three Sides of a Triangle : ");
  	scanf("%d%d%d", &side1, &side2, &side3);
  	
  	if(side1 == side2 && side2 == side3)
  	{
  		printf("\n This is an Equilateral Triangle");
 	}
 	else if(side1 == side2 || side2 == side3 || side1 == side3)
 	{
 		printf("\n This is an Isosceles Triangle");
	}
	else
	{
		printf("\n This is a Scalene Triangle");
	}  
 	return 0;
 }
