Relating Lines to Planes - Lesson 6-1

Today, we began to look at lines and planes and how they relate in space. Remember that space (...the Final Frontier!!...) is defined as the set of all points, so we're talking 3D here, not just 2D, like most of the rest of the year. We started with a definition (the foot of a line intersecting a plane), three postulates, and three theorems. These all have to do with the way that lines and planes intersect.

Theorems 44-46


We then looked at the following example. See if you can do it (the answers are below!).
