Which of the following options does NOT give the lengths of three sides of any triangle?
Answer & explanation
Correct answer: option 2
Three sides form triangle iff
Sum of two sides of triangle > Third side
Lets solve it one by one for each option :-
A. 12, 18, 25
12 + 18 > 25
30 > 25
B. 18, 23, 41
18 + 23
= 41
( It is 41 which is equals to third not greater than 3rd side )
So, we find the group of 3 sides that do not form a triangle.
No need to solve further
Answer :- B. 18, 23, 41
