GeoGebra Animation Tool
find the image(yes) + find co-ordinates of the object under rotation(describe paper rotation compared to animated rotation).
find the angle and direction of rotation(yes with instruction or a class in GeoGebra)
find the centre of rotation (yes)
length from the centre of rotation(yes, additional learning)
How you used launch mathematics success for this topic (big jump unable to see incremental changes, animation in GeoGebra help us with this) …GeoGebra is a powerful animation mathematics tool.
Create one vector
Create an object
After dealing with vector direction then
Then by varying the vector the image position will vary as well from the original position to a new position base on the vector. This allow students to stress test translation.
- Students can state a vector, and other students give the co-ordinates of the image.
- Find the image
- Find the vector(check)
- Find the object given the image

- vector responsible
- reflection(draw the lines and click on object then line for the reflection) so remove the reflection lines and have students click on the reflection line they want

- describe by centre and scale factor
- find centre
- find k

Mathematics is art and science, not only science but art as well.
direction is very important (use of GeoGebra for high level vector problems)
note all the computer related things you must consider setting up the questions that have nothing to do with solving the question directly + we are able to reap the benefits more readily from transformation because once it is set up, I t is easy to harvest the benefits of using the transformation. So, it isn’t easy to animate mathematics in an easy way.
Hence the need to use more than one animation tool because what works well with one tool doesn’t work so well with another tool.
Not sure what to do in GeoGebra for vectors videos online not saying much yet.
Hard to work with and representing vectors without touching are drawing on it to help us understand it; handicapped by not being able to do the drawing on the diagram with pencil and erasing, or adjusting which is a given aspect of problem solving vectors. (students required to draw).
A lot is said about motion: GeoGebra animation show a flow of movements for transformation and in these cases I would expect to register the highest results in students’ performance.
Please help if you can.
