1. 1.1b Points, Lines and Planes Students will use points, lines and planes to model every day items. Students will identify collinear and coplanar points and intersecting lines in space.

2. Intersections The intersections of two lines is a ___________. What is the intersection of two planes? How do I draw this?

3. Example 1 How many planes are shown in the figure? How many planes shown contain points both F and E? Name four points that are coplanar. Are E, D, A and C coplanar? What is the intersection of plane EBC and CDF? What is the intersection of plane ABC and EBD?

4. Stations With your partner, complete the stations. Both of you have to show all your work!! When you are done, put your name on it and turn it in. There are a total of four stations worth 8 points. (2 each).

5. Station I 1.Name a plane._______ 2.Name 3 collinear points._______ 3. intersects the plane at what point?_______ 4.Name 4 coplanar points._______ 5.Name another way._______

6. Station II 1.How many planes are shown in the figure below? 2.Name a point not on plane TNB. 3.What is the intersection of plane XHB and plane JXB?

7. Station III Nate’s mom wants him to stop at the grocery store on the way home from school. She says this should be easy since the three places are collinear. Draw a map marking out Nate’s route.

8. Station IV Draw the figure described in each statement: 1.Draw line m and line p intersect at C. 2.Draw planes ABC and planes CBE intersect at.
