Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm is a right triangle?

The triangle is a right triangle because 52 + 122 = 132.
The triangle is a right triangle because 5 + 13 > 12.
The triangle is not a right triangle because 52 + 132 > 122.
The triangle is not a right triangle because 5 + 12 > 13.

Answer:   the triangle is a right angle triangle. I can't see the correct explanation  here so I will explain    Step-by-step explanation:   to work out whether triangles are right angle you do :   square root of (5² + 12²) so it would be 25 + 144 =169 and the square  root of 169 is 13  . we do this because  the square  root of both of the side lengths squares should make ths longer side in this case it makes 13 so it is a right angled triangled        i hope this helps . if you need any more help  pls ask :)
