#include<graphics.h>

#include<math.h>

void show(float a[][3]){

}

printf("Enter the coordinates of triangle:\n");

for(int k=0;k<3;k++){

printf("Enter the coordinates:\n",k+1);

scanf("%f%f",&a[k][0],&a[k][1]);

a[k][2]=1;

}

setcolor(WHITE);

return 0;

}


OUTPUT:


Enter the coordinates of triangle:

Enter the coordinates:

50 50 100 150 150 50
