    Direction: David folds a sheet of paper. The dotted lines as shown in the figure are the creases formed, which are named as l, m and n. What can you say about lines I and n?

    A)  \[l//n\]

    B)  \[l\bot n\]  

    C)  I is the same line as n

    D)  Neither [a] nor [b]

    Correct Answer: B

    Solution :

     A \[{{90}^{o}}\] angle is formed at the intersection of l and n. So \[l\bot n\].
