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");
}
}
}
