Perpendicularity of a Line and a Plane - Lesson 6-2

Today, after going over the 6.1 homework, we discussed what it means for a line to be perpendicular to a plane. We started with a definition for this situation and then a theorem that makes proving it a little easier:

Line Perp to Plane Definition & Theorem


We then went over the following example. Note that the plane should be labeled m in the diagram! should make sure you understand how we used Theorem 48 and how we used the converse of the equidistance theorem!!



This stuff really shouldn't be too bad for you...the key is being able to "see" the other words...make sure you can see how the diagrams lines relate to the planes and what the shapes really look like.
