-5,12,13 If You use the Pythagorean theorem for the first three you can find out which ones would be triangles. The last one you know can’t be a triangle because there’s four lines. The Pythagorean theorem is a squared plus B squared equals C squared so you would plug in your numbers in that formula and see if it is a true statement.
