1.  Name a line and a plane in the picture below:

2. LEQ: What are segments and rays and how are they named? What are parallel lines and planes?

3.  Segment: part of a line, has exactly two endpoints  Drawing  Symbol  Name: “segment AB”

4.  Ray: part of a line, has exactly one endpoint with other end extending in opposite direction  Drawing  Symbol  Name: “Ray AB”

5.  Opposite rays: Two rays that share a common endpoint and extend in opposite directions

6.  Parallel lines: Two identical lines that never intersect.  Symbol: ll m ll f

7.  Skew lines:  Two lines that never intersect but are not parallel.

8.  Parallel Planes identical planes that don’t intersect  Planes ABCD and EFGH are parallel

9. Line symbol:

10.  Segment  Ray  Opposite rays  Skew Lines  Parallel Planes  Parallel Lines

11.  Name all segments and rays in the figure. Name any opposite rays

12.  Name all the parallel planes in the figure below:

13.  Name all segments parallel to AE.  Name all segments skew to AE.  Name all segments parallel to DC.  Name all segments skew to DC. A C B D F H E G

15.  P. 25-27: 1-15 odd, 16-23, 38
