It looks as if P might be equidistant fromF and X. Is it?

For the following coordinates of two points on a number line, state the distance between the points 2 and .
The plane that contains the top of the box can be called plane ABCD.
A plane can be named by three or more non-collinear points it contains. In chapter 12 you will study pyramids like the one shown at the right below.

Name a line and a plane that intersect in a point.
Make a sketch showing four coplanar points such that three, but not four, of them, are collinear.
