Answer:
first option
Step-by-step explanation:
let the point of intersection of the two sticks be 'O'
then, get back to the question,
isha wants KM=KN--------- 1
and LM=LN------ 2
for eqn.1,
in ΔKON and ΔKOM
if, ∠KON=∠KOM -------- 3
and MO = NO, -----4
since KO is common
therefore ΔKON ≅ ΔKOM
but eqn.3 and eqn.4 are only possible
if KN is perpendicular to MN and it bisects MN
similarly, for eqn.2
in ΔLOM and ΔLON
they would be congruent only
if KN is perpendicular to MN and it bisects MN
hence, first option
(pls ask for doubts if any
