 Do you need a full course of geometry?

Complete this course and the second semester course and you will have a very good understanding of 2 dimensional ( a little bit of 3 dimensional) geometry.





If you are a visitor you have limited access.  You may view Lessons 2-2, 3-2, Activity 4-5, Lesson 5-1, and Activity 5-2,  see below.



WHERE do you begin ?  Where is the first LESSON?


If you are a new student  Click here to watch Video explaining how to begin your first lesson and assignment.

On the right side of these pages you should see a box called the NAVIGATOR

Within the NAVIGATOR box you should find most all that you need in the folders LESSONS and STUDENT.   If you do not see the NAVIGATOR, then along the right side, near the search box above, look for a  small black triangle.  Click it and the NAVIGATOR box will appear.
