In the given figure, name the pairs of parallel, intersecting, perpendicular, and concurrent lines.
Parallel lines do not intersect even on producing it,they do not have any point in common and the distance between them is same.
If two or more lines intersect each other at one point,then they are called intersecting lines
If two lines intersect at right angles then they are called perpendicular lines
Three or more lines passing through the same point are said to be concurrent lines
Hence, in the figure
a pair of parallel lines are
a pair of intersecting lines are
a pair of perpendicular lines are
concurrent lines are
