If you overload students with information on harder concepts, students get very confused very fast. When we define words, we ordinarily use simpler words, and these simpler words are in turn defined using yet simpler words. Specifying planes in three dimensions geometry video.

These form the building blocks for the first theorems that students can prove. Once this is done, students can continue working on the activity from the previous lesson called points, lines and planes. A part of a line that has defined endpoints is called a line segment. It can be extended indefinitely in both directions.
