Question 2

Which collection of three side lengths will NOT form a triangle?


6 in, 10 in, 18 in


10 in, 12 in, 15 in


10 in, 15 in, 6 in


10 in, 18 in, 12 in

Answer 1

6 in, 10 in, 18 in
The sides need to be in between (10-6) and (10+6) or between 4 and 16. But the third side here is 18, so that cannot qualify as a side.

Hope this helps.

Answer 2

Side lengths with 6 in, 10 in, 18 will not form a triangle 'cause we know, that sum of shorter sides must be greater than the longer side but here it's not.

In short, Your Answer would be Option A

Hope this helps!
