Question

is overleftrightarrow{pn} parallel overleftrightarrow{km}? explain.

no, the two lines intersect, so they cannot be parallel.
yes, the two lines intersect at a right angle, so they are perpendicular.
yes, the two lines do not intersect, so they are parallel.
no, the two lines do not intersect at a right angle, so they cannot be parallel.

Explanation:

Step1: Recall the definition of parallel lines

Parallel lines are lines in a plane that do not intersect.

Step2: Analyze the given lines

Looking at the lines \(\overleftrightarrow{PN}\) and \(\overleftrightarrow{KM}\), we can see that they intersect.

Answer:

no, The two lines intersect, so they cannot be parallel.
