GSP Construction Tools

I have to say that I am enjoying using Geometer's Sketchpad to do constructions. Over the course of this first semester in geometry and in this class, I have had a chance to do a bunch of cool constructions and explorations using GSP. Some of these constructions are really involved and took me a long time to get to work correctly. Others are pretty simple to understand and easy to replicate. Either way, it is always better to work smarter than harder. With that in mind, here is a GSP file with the following list of construction tools available on it.

1. Centroid

2. Orthocenter

3. Circumcenter

4. Circumcircle

5. Incenter

6. Incircle

7. Medial triangle

8. Orthocenter, Mid-segment triangle.

9. Orthic triangle

10. Pedal triangle

11. Center of Nine point circle

12. Nine Point Circle

13. Trisecting a line segment

14. Equilateral triangle, given a side

15. Square, given a side

16. Isosceles triangle, given base and altitude

17. Triangle Centers (H, G, C, and I)

18. Triangle Centers with Euler Line

19. Divide a segment AB into two parts that form a golden ratio.

20. Pentagon, given a side.

21. Hexagon, given a side.

22. Octagon, given a side.


Keep in mind that this list will evolve as I learn and do more cool stuff. So, check back periodically to get some more excellent construction tools.
