Sheradon.burkett 2 years ago HELP almost done with the test... 10 minutes left! Which of the following lengths could be the sides of a triangle? 7 cm, 18 cm, 12 cm 13 cm, 22 cm, 7 cm 22 cm, 13 cm, 8 cm 18 cm, 6 cm, 12 cm I have looked all through out my book, and can not find a single lesson about this... any help what so ever would be greatly appreciated! :)

The sum of any two sides must be greater than the third side.

Find a group of choices that has a small number compared to the others. Then add the smallest side to the secondestone. If the sum is not greater than the third side, that's the one that's not a triangle.
