(c) a slanting line Horizontal line Vertical line Slanting line

A pair of lines lying in a plane either meet at a Note
point or never meet to each other. On this basis, A plane can be

lines.

The point at which the lines meet or intersect is called the point of intersection. l m
In the given figure, O is the point of intersection of lines l and m. O

Parallel Lines: A pair of lines that can never meet even if extended in both
the directions endlessly are called parallel lines.
p
In the given figure, p and q are parallel lines. q

Think and Answer
Where do you see parallel lines around you? Write in the given blank spaces.
