```cpp
#include <stdio.h>
#include <stdlib.h>
int main()
{
int a,b,c;
scanf("%d %d %d",&a,&b,&c);
double A,B,C;
A=1.0*(b*b+c*c-a*a)/(2.0*b*c);
B=1.0*(a*a+c*c-b*b)/(2.0*a*c);
C=1.0*(b*b+a*a-c*c)/(2.0*b*a);
if ( a+b<=c||a+c<=b||b+c<=a ){
printf("Not triangle\n");
}else{
if ( A==0.0||B==0.0||C==0.0 ){
printf("Right triangle\n");
}else if ( A>0.0&&B>0.0&&C>0.0 ){
printf("Acute triangle\n");
}else if ( A<0.0||B<0.0||C<0.0 ){
printf("Obtuse triangle\n");
}
if ( (a==b&&a!=c)||(a==c&&a!=b)||(b==c&&b!=a) ){
printf("Isosceles triangle\n");
}else if ( a==b&&a==c&&b==c ){
printf("Equilateral triangle\n");
}
}
return 0;
}

等边三角形也算等腰三角形，还有每次输出完要换行

@[__Tonycyt__](/user/667037) 感谢大佬，确实看完发现等边还要求包括在等腰内部♪(･ω･)ﾉ
