Which are the possible side lengths of a triangle?
3 cm, 5 cm, 9 cm
4 cm, 8 cm, 10 cm
6 cm, 9 cm, 17 cm
8 cm, 10 cm, 18 cm

Respuesta :

The answer would be B: 4 cm, 8 cm, and 10 cm. The first two lengths, when added together, should equal MORE than the last length. If they do not equal more, the lengths will not make a correct triangle.

Hope this helps!!!!
