What is the important idea?
Translation
-
Open GeoGebra.
-
Change the view to Geometry.
-
Create a quadrilateral.
-
Create an arbitrary vector.
-
Translate the quadrilateral by the vector.
- ⚠️Do not close the windows⚠️
Rotation
-
Open (a new window of) GeoGebra.
-
Change the view
to Geometry. -
Create a quadrilateral.
-
Create a point outside the quadrilateral.
-
Rotate the quadrilateral around the point by an angle of 180° (counter clockwise).
- ⚠️Do not close the windows⚠️
Static transformation
Static Dynamic transformation
-
Go to the Translation GeoGebra file.
-
Create a slider:
-
Name: animate
-
Number.
-
Interval: 0 to 1.
-
Increment: 0.1
-
-
Show the Input Bar.
-
Animate the translation:
Translate [q1,u*animate] -
Change the value of the slider.
-
Go to the Rotation GeoGebra file.
-
Create a slider:
-
Name: animate
-
Angle.
-
Interval: 0° to 180°.
-
Increment: 1°
-
-
Show the Input Bar.
-
Animate the rotation:
Rotate [q1,animate,E] -
Change the value of the slider.
Basic animation
Basic Concatenated animation
-
Go to the Translation GeoGebra file.
-
Modify the animate slider:
-
Interval: 0 to 2.
-
-
Create a second vector.
-
Animate the second part of the animation:
Translate(q1', v * If(0 ≤ animate < 1,0,If(1 ≤ animate < 2, animate - 1))) -
Change the value of the slider*.
-
Create the SFX 📽️:
- Redo the first part on the animation.
- Modify the visibility of the objects.
-
Open (a new window of) GeoGebra.
-
Change the view
to Geometry. -
Create a right triangle.
-
Create the squares on their sides.
-
Do the dissection.
- ⚠️Do not close the windows⚠️
-
Create a single polygon for each dissection.
-
Trace the necessary vector.
-
Modify the animate slider:
-
Interval: 0 to 5.5
-
-
Animate each dissection in a concatenated way.
Grazie mille!
