Geometry Online 

​​​Geometry is a full year, high school math course for the student who has successfully completed the prerequisite course, Algebra I. The course focuses on the skills and methods of linear, coordinate, and plane geometry.

These supplementary videos are in addition to the video instruction of your online lessons and work with the Academy teachers. They are not the curriculum but are aligned to the daily lesson material. Students should work in their online curriculum, with their NFC Academy teacher and use these videos in their learning process as needed.
