Copy of Points, Lines, and Planes
In order to start our journey into Geometry, we first have to understand the meaning of some key terms!
Part 1
Part 2: Intersections between two lines
Take a few minutes to mess around with the toolbar below. Create a point, draw a line, make a triangle, draw a picture! Have fun! Then answer the following question: There are three cases of relations ("intersections") between two lines. What are they? Show one case using the toolbox below! Remember that a line is determined by two points, so start by adding two points before drawing a line between them.
Part 3: Intersections of a plane with a line
1. In the image below, where does line intersect plane P?
2. Where does line intersect plane P?
Part 4: Intersecting Planes
1. Where does plane A intersect with plane B?
2. There are two other cases of relations between two planes. What are they? [Hint: Think about two pieces of paper with "edges" that extend infinitely in all four directions of the paper.]
Use the slider above to explore parallel planes
3. When will the 2 parallel planes intersect?
