C Exercises: Check three sides of a triangle form a right triangle or not

C Basic Declarations and Expressions: Exercise-134 with Solution

Write a C program to check whether three given lengths (integers) of three sides of a triangle form a right triangle or not. 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

Sample Solution:

C Code:

#include <stdio.h>
int main()
 {
  int x,y,z;
 
     printf("Input the three sides of a trainagel:\n");
 
     scanf("%d %d %d",&x,&y,&z);  
 
     if((x*x)+(y*y)==(z*z) || (x*x)+(z*z)==(y*y) || (y*y)+(z*z)==(x*x) )
         {  
		     printf("It is a right angle triangle!\n");  
	}
       else
         { 
		  printf("It is not a right angle triangle!\n"); 
		  }
    return 0;
}

Sample Output:

Input the three sides of a trainagel:
12
11
13
It is not a right angle triangle!

Previous: Write a C program to calculate the sum of two given integers and count the number of digits of the sum value.
Next: Write a C program which reads an integer n and find the number of combinations of a, b, c and d (0 <= a, b, c, d <= 9) where (a + b + c + d) will be equal to n.
