By Kevin Perry

The Script Tool

In this assignment, some basic Geometer’s SketchPad script tools are listed for future use. Each link will download the file that contains a script tool that completes the required construction.

1. Centroid

2. Orthocenter

3. Circumcenter

4. Circumcircle

5. Incenter

6. Incircle

8. Orthocenter, Mid-segment triangle

10. Pedal triangle

11. Center of Nine point circle

14. Equilateral triangle, 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. Locus of vertex of a fixed angle that subtends a fixed segment

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

Conclusions and
Extensions

There are many more script tools that can be completed that will be helpful for mathematical proofs or discussions. This page will continue to be a depository for some interesting and useful construction tools..
