Question

Meant to be written in Java JDK 14.0

Three double variables a, b, and c represent the length of 3 sides of a triangle. Write a program to determine if the triangle is right triangle. Find the hypotenuse side first.

Answer 1

import java.util.Scanner;

public class CheckRightTriangle {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter lengths of three sides of a triangle: ");
        double a = in.nextDouble();
        double b = in.nextDouble();
        double c = in.nextDouble();
        if (a*a == b*b + c*c || b*b == a*a + c*c || c*c == a*a + b*b) {
            System.out.println("This triangle is a right triangle");
        } else {
            System.out.println("This triangle is not a right triangle");
        }
    }
}
