Integers and booleans. Write a program RightTriangle that takes three int command-line arguments and determines whether they constitute the side lengths of some right triangle. right triangle The following two conditions are necessary and sufficient: Each integer must be positive. The sum of the squares of two of the integers must equal the square of the third integer.

The programming language is not stated;

I'll answer using C++

#include<iostream>

#include<cmath>

using namespace std;

int main()

{

int side1, side2, side3;

cout<<"Enter the three sides of the triangle: "<<endl;

cin>>side1>>side2>>side3;

if(side1<=0 || side2 <= 0 || side3 <= 0) {

 cout<<"Invalid Inputs";

}

else {

 if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

 cout<<"Right Angled";

 }

 else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

 cout<<"Right Angled";

 }

 else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

 cout<<"Right Angled";

 }

 else {

 cout<<"Not Right Angled";

 }

}

return 0;

}

Explanation:

The following line declares the three variables

int side1, side2, side3;

The next line prompts user for input of the three sides

cout<<"Enter the three sides of the triangle: "<<endl;

The next line gets user input

cin>>side1>>side2>>side3;

The following if condition checks if any of user input is negative or 0

if(side1<=0 || side2 <= 0 || side3 <= 0) {

 cout<<"Invalid Inputs";

}

If otherwise

else {

The following if condition assumes that side1 is the largest and test using Pythagoras Theorem

if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

 cout<<"Right Angled";

 }

The following if condition assumes that side2 is the largest and test using Pythagoras Theorem

 else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

 cout<<"Right Angled";

 }

The following if condition assumes that side3 is the largest and test using Pythagoras Theorem

 else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

 cout<<"Right Angled";

 }

If none of the above conditions is true, then the triangle is not a right angles triangle

 else {

 cout<<"Not Right Angled";

 }

}

return 0;

i think so.
