**Problem :-**Write A C++ Program To Find Triangle Is Equilateral Isosceles Scalene Angled.

**Logic :-**Below i written all the condition see and apply in programming

**Equilateral :-**

**If All The Side's (A,B,C) of Triangle is equal means if A=B=C then triangle is Equilateral.**

**Isosceles :-**

**If Two Sides of Triangle Is Equal In length means if A=B or B=C And C=A then triangle is Isosceles.**

**Right angled :-**

**Containing or being a right angle ,means a*a==b*b+c*c Or b*b==c*c+a*a Or c*c==a*a+b*b any one of Condition is true then it is Right angled Triangle.**

**Scalene :-**

If All Side's are Unequal Then It is Scalene Triangle .

**Solution :-**

**#include<iostream>**

using namespace std;

int main()

{

int a,b,c;

cout<<"Enter The Value Of a,b,c \n";//side's of triangle

cin>>a>>b>>c;

if(a==b && b==c && c==a)

{

cout<<"The Triangle is Equilateral\n");

}

else if(a==b || b==c || c==a)

{

cout<<"The Triangle is Isosceles\n");

}

else if(a*a==b*b+c*c ||b*b==c*c+a*a || c*c==a*a+b*b)

{

cout<<"The Triangle is Right angled\n");

}

else

{

cout<<"The Triangle Scalene angled\n");

}

return 0;

}

**Output:-**

Thanks a lot your programming code is neat and clean, and I mostly like the way of explanation of the program. I have also gone through Hacker Rank Programming Solutions are also great for learning and implementing the logic. Thanks again and Keep it up.
