Write-up 7 is to investigate tangent circles. Time does not permit me to elaborate extensively on tangents. Using GSP will give the teacher many creative diagrams to fascinate young minds. The fascination of GSP works well with tangent circles and all geometric applications. I will not do too much more verbage. I was pressed for time and did not get to explore this as much as I would have liked (or you wanted). I have watched Mike P's elaborate diagrams through the semester and realize the eye-catching potential of this exercise. I apologise. Between 2 jobs, a family, officer duties at a club, and coursework, I blended everything as well as I could. I enjoyed the course(even with all the frustrations of lost work) and learned a lot.
