Pythagoras Meets Dynamic Software and a Digital Camera Summary

Outline
• Some comments about GSP
• Getting Started: Some menus and commands
• Dragging: The Transformation Menu
• Repeating the same construction? No way! Use a Script
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.
The tool palette
The menus
The Construct Menu
The Transform Menu
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.
• Repeating the same construction….
• No way! Use SCRIPTS
Equilateral Triangle, Construction
• Using ruler and compass, construct an equilateral triangle.
• Repeat the same construction in GSP
• CREATING A SCRIPT
