Question

How are lines KL and MN related? The lines intersect at point K. The lines are parallel. The lines are perpendicular. The lines do not have slopes.

Answer 1

Since the two lines meet each other they should be perpendicular.

Option  b

Explanation:

• when two lines meet each other they can never be parallel to each other. This is because parallel lines have a constant distance between the two line segments and the line segments do not intersect each other. Since the two lines meet each other the slopes of the two line must be different

• so if we consider the slope of any one line to be zero the slope of the other line must be not equal to zero. Hence the correct answer is that they are perpendicular
