Question

In a right triangle, the square of the length of one side is equal to the sum of the squares of the lengths of the other two sides. Write a program that prompts the user to enter the lengths of three sides of a triangle and then outputs a message indicating whether the triangle is a right triangle.

Answer 1

Answer:

#include <iostream>

using namespace std;

int main(){
int a,b,c;
cout<<"Input firstside: ";
cin>>a;
cout<<"Input secondside: ";
cin>>b;
cout<<"Input thirdside: ";
cin>>c;
if((a*a+b*b==c*c)||(a*a+c*c==b*b)||(c*c+b*b==a*a))
cout<<"Triangleis right"<<endl;
else
cout<<"Triangleis not right"<<endl;
return 0;
}

Result:
Input first side: 3
Input second side: 4
Input third side: 5
Triangle is right
