C program to check whether the triangle is right angled triangle

 c program to check whether the triangle is right angled triangle

• To check right angle triangle or not first we need to check sum of all three angles 
• If sum of all three angles is 180 then we it should satisfy second condition also
• Second condition is on of the angle should be 90.
• if both the conditions are passed then we can say it is a right angle triangle.
• Now lets write a c program to check triangle is right angle triangle or not.

1. #include<stdio.h>
2. // write a c program too check traingle is right angle triasngle or not
3. //www.instanceofjava.com
4. int main()
5. {
6.      int angle1,angle2,angle3;
7.      printf("Enter Three Angles of Triangle");
8.      printf("\n-------------------------------\n");
9.      printf("Enter Angle1  : ");
10.      scanf("%d", &angle1);
11.      printf("\nEnter  Angle2 : ");
12.      scanf("%d",&angle2);
13.      printf("\nEnter  Angle2  : ");
14.      scanf("%d",&angle3);
15.      printf("--------------------------------\n");
16.      if(angle1+angle2+angle3==180) 
17.      {
18.          
19.           if(angle1==90 || angle2==90 || angle3==90)
20.           {
21.                printf("\nTriangle is Right Angle Triangle\n"); //
22.           }
23.          
24.      }
25.      else
26.      {
27.           printf("\nIts Not a Triangle ");
28.      }
29.     getch();
30. }
