Question

which lines are parallel? justify your answer. mb and ng are parallel by the no lines mn and bg

Explanation:

Step1: Recall parallel - line criteria

Parallel lines have equal corresponding angles, alternate - interior angles, etc. In the given figure, if we assume that the angles formed by the transversals with the lines are equal in a way that satisfies parallel - line postulates. Here, if we consider the horizontal lines, MN and BG are parallel because they are horizontal lines and the concept of parallel lines in a plane states that two lines with the same slope (in this case, slope = 0 for horizontal lines) are parallel.

Answer:

MN and BG
