GeoGebra

This is where I'll post or link to GeoGebra files.

(For more info on GeoGebra in this workshop: see What to Bring.)

Isometries

Dilation

Introduction to transformations

Composition

Complex numbers and matrices

Teacher's notes on these files.

Only four basic isometries

In most of those files I use the convention: orange for the original (pre-image), indigo for the image.
