Write a program to check Right angle triangle In java

 

Question:

Write a Java Program to accept three positive Integers as input and check whether the given numbers farm a right angle Triangle or not. If the input numbers form a triangle print “RightAngle Triangle” else “Not a right-angle Triangle”.

In case of zero or negative inputs print “Invalid”.Note: Rule to form a right-angle triangle is, the sum of squares of any two numbers should be equal to the square of the third number.

Sample Input 1:

Enter three sides:

3

4

5

Sample output:

Right-Angle Triangle

Sample Input 2:

Enter three sides:

32

0

5

Sample output 2:

Invalid

Code:

import java.util.Scanner;

public class right_angle_triangle {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        System.out.println(“Enter three sides:”);

        int a = sc.nextInt();

        int b = sc.nextInt();

        int c = sc.nextInt();

        if(a>0 && b>0 && c>0){

            int a1 = a*a;

            int b1 = b*b;

            int c1 = c*c;

            if(c1== a1+b1 || b1==a1+c1 || a1==b1+c1){

                System.out.println(“Right-Angle Triangle”);

            }

            else {

                System.out.println(“Not a right-angle Triangle”);

            }

        }

        else{

            System.out.println(“Invalid”);

        }

    }

}
