Answer the questions using
1.3 Segments, Rays,
Parallel Lines and Planes
Learning Target
I
can identify segments, rays, and
parallel lines given geometric
figures.
 Segment
– part of a line
consisting of two endpoints and
all points between them.
 Ray
– part of a line consisting of
one endpoint and all the points
of the line on one side of the
enpoint. (Direction is important)
 Opposite
Rays- two collinear rays
with the same endpoint. Opposite
Rays always form a line.
 Lets
practice naming segments
and rays (remember notation)

Learning Target
I
can identify segments, rays, and
parallel lines given geometric
figures.
Parallel Lines – coplanar lines that do
not intersect
 Skew lines – noncoplanar lines (they are
not parallel and they do not intersect)
 Examples

 Identify
some parallel lines and
some skew lines.
Parallel Planes – Planes that do not
intersect

WARNING: This will be your only
warning
 You have a homework quiz tomorrow on
1-1 to 1-3
 Homework quizzes are problems taken
directly from your homework, so if you
stay on top of your classwork/homework,
you will not have a problem with this.
