When two lines meet, they intersect. Look at the
two intersecting lines below. Line DC intersects with Line ST.
When two lines intersect to form right angles, we call
them perpendicular. Lines EF and WX are perpendicular.
Two lines that never intersect are called parallel
lines. Lines MN and RT are parallel lines.
Identify the perpendicular and parallel lines below.
Parallel lines V
and Q.
Intersecting lines C
and S.
Line YX is

The intersection of ray AF and ray YX form four
angles.
Line W
is
to line S.
Line C
lines SF and WI
