    • 7. Project -Dynamic Square – Make a regular polygon with 4 sides 7
    • 8. Dynamic Square • Definitions of a square? – Regular polygon with 4 sides • GeoGebra: Regular polygon tool 8
    • 9. Dynamic Square – With active • Click once to get Point A. • Click again to get Point B. • Dialog box will open … 4 is there… click on OK. 9
    • 10. Square Dynamics – CLICK on the Move tool – You can click and drag point A or point B. – The square is ALWAYS a square. 10
    • 11. Square Dynamics – You can click and drag the square itself. This will only move the square - the dimensions of the square depend on A and B! - Try to click and drag point C or point D. – Why can’t you click and drag points C or D? – Answer: They are dependent on A and B. 11
    • 12. • Many, many applications – Ready to use applets are available. – Is easy to use, powerful and dynamic. – Teachers can use it to better understand what they are teaching. – Teachers and students can freely use it anywhere. – Students can build animations, simulators, … Why GeoGebra?
