Teaching Geometry - Chapter 2: Parallel Lines

In the previous section, we started off with individual objects like lines and planes then took a step up to two objects (rays) and combined them together to make a new object (an angle). In this section, we're going to continue that process by looking at the relationships that can exist between multiple lines.

Teaching Geometry

Technologies Used

We try to limit the technologies that are used in each classroom to the minimum required to get the job done. The combinatorics classroom uses only JavaScript which all modern browsers support.

Source Material

The material in this classroom is substantially identical to Teaching Geometry. The only significant difference is that this online version doesn't contain the complete solutions to the source text's exercises that the printed version has. This was a conscious decision on our part since we felt that some parents might not want the solutions being available to their students. We've also added a brief introduction to each Chapter in the online version that we think helps to set up the context which isn't necessary when the physical textbook is being used as a companion to the student's text.
