State if each set of three numbers can be the lengths of the sides of a triangle and explain why and how you got the answer.

13, 12, 26

Respuesta :

No. It's no because if you do the correct math, you can see when you add the first side, 13 and 12, you get 25. 25 is < 26. All sides have to have a correct amount to be a triangle.

12+26>13
38>13 YES

13+26>12
