Homework 1: Triangle Angles

Your task

Write a program that checks the given three angles of a triangle, and returns whether the triangle angles are valid, or not.

The triangle angles can also be decimal numbers, so please use the variable type double.

Output: Print The triangle is valid. or The triangle is invalid., depending on the given angles.

Example cases

Use these original example cases to check your program.

Check: Run your program with both sets of angles. The message should change because your program checks the values, rather than because you edited the output statement.

Starter code

Create a file named Homework1.java. The filename must match public class Homework1. Fill in your name and date, then write your solution inside main.
