1. WARMUP
Enter Room #
Answer the questions using always, sometimes, or never

2. 1.3 Segments, Rays, Parallel Lines and Planes

3. Learning Target
I can identify segments, rays, and parallel lines given geometric figures.

4. 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)

5. Opposite Rays- two collinear rays with the same endpoint
Opposite Rays- two collinear rays with the same endpoint. Opposite Rays always form a line.

6. Lets practice naming segments and rays (remember notation)

7. Khan Academy Geometry Points lines and planes
Recognizing rays, lines, and line segments

9. Learning Target
I can identify segments, rays, and parallel lines given geometric figures.

10. Parallel Lines – coplanar lines that do not intersect
Skew lines – noncoplanar lines (they are not parallel and they do not intersect)
Examples

11. Identify some parallel lines and some skew lines.

12. Parallel Planes – Planes that do not intersectEX

13. In your groups, do 7-9 on 1-3 worksheet

14. Now do 10-13

16. 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.
