Warm up Draw a diagram or write a paragraph representing how you think points lines and planes relate to each other. When you get done: Finish your points and lines picture and turn into box

Math antics points, lines, and planes

Exploration: Draw two different points on your paper. Connect the points on your paper. How many different ways could you connect those two points using straight lines?

Postulate: Through any two points there is exactly one line that can pass through them both

Exploration: Draw one line on your paper. Make an intersecting line. How many different points could the same lines intersect at at the same time?

Postulate: If two distinct lines intersect, then they intersect in exactly one point

Exploration: Using the 2 planes I gave you make an intersection of planes. How many lines would the 2 planes share? What conclusion can you come to about shared lines in planes?

If two distinct planes intersect, then they intersect in exactly one line Postulate:

Vocabulary: Collinear – points that lie on the same line Noncollinear – Coplaner – Noncoplaner –

Exercise : name some planes A. B. C.. D E. F.
