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
