  1. Pythagoras Meets Dynamic Software and a Digital Camera Summary Armando M. Martinez-Cruz Amartinez-cruz@fullerton.edu CSU-F Paul Sexton psexton@fjuhsd.k12.ca.us Buena Park High School

  2. Outline • Some comments about GSP • Getting Started: Some menus and commands • Dragging: The Transformation Menu • Repeating the same construction? No way! Use a Script

  3. Some Comments: • Software is extremely friendly, powerful and self-contained, but not perfect. • The power of the software lies on the ability to preserve the properties of Euclidean constructions when figures are dragged. • Strong tool for pedagogical purposes. • Constructions can be copied and pasted in other program documents but they become static. • Photos can be pasted in GSP docs. • Mathematical investigations are enticed. • Also good for analytic geometry.

  4. The tool palette

  5. The menus The Construct Menu

  6. The Transform Menu

  7. Dragging is not a Drag • Construct • Transform • Drag • The math is underneath Construct a human like figure using the circles and segments. Select (ie, mark) a line of reflection, and use the transform menu to reflect your figure. Then drag some (or all) parts.

  8. Repeating the same construction…. • No way! Use SCRIPTS

  9. Equilateral Triangle, Construction • Using ruler and compass, construct an equilateral triangle.

  10. Repeat the same construction in GSP

  11. CREATING A SCRIPT

  12. The Custom Tool
