You can put this solution on YOUR website! can 7, 8, 18 be a measurment of a triangle
---
Ans: No, because 7+8 is less than 18
---
Try it. Let a line segment be 18
Start a legment of length 7 on one end
and a segment of length 8 on the other end.
Notice that they cannot meet to form a triangle
because 7+8 < 18.
