Exploring Intersections of Planes
Complete the following in the app below.
 | Plot 3 points anywhere. Click on a point to toggle moving up-down & left-right. |
 | Construct a plane that passes through these 3 points. |
 | Construct the intersection of the two planes you see here. |
 | Move any 1 (or more) of the points around. Click on a point to toggle moving up-down & left-right. |
Suppose 2 planes intersect. How would you describe their intersection?
Suppose plane A and plane B intersect at k. What can we conclude about k?
