Program to accept 3 angles and check if is it of a triangle. If yes, also find type of the triangle.
#include<iostream.h>
#include<conio.h>
void main()
{
int flag1,flag2,flag3;
flag1=flag2=flag3=0;
float angle1,angle2, angle3;
cout<<"Enter 1st Angle : ";
cin>>angle1;
cout<<"Enter 2nd Angle : ";
cin>>angle2;
cout<<"Enter 2nd Angle : ";
cin>>angle3;
if(angle1+angle2+angle3==180)
{
if(angle1==angle2&&angle2==angle3)
{ cout<<"\n\nGiven angles are of equilateral triangle."; }
if(angle1==angle2||angle2==angle3||angle1==angle3)
{ flag1=1; }
if(angle1!=angle2 && angle1!=angle3)
{ flag2=1; }
if(angle1==90||angle2==90||angle3==90)
{ flag3=1;}
if(flag1==flag3)
{ cout<<"\n\nGiven angles are of a right angle isosceles triangle."; }
if(flag2==flag3)
{ cout<<"\n\nGiven angles are of a right angle scalene triangle."; }
}
else
{ cout<<"\n\nGiven angles are not of a triangle."; }
getch();
}
