Transforming Polygons (templates, repeated practice, visualizers)

Screens 1 - 4: Templates for translation, rotation, reflection, and dilation problems. Change the values in graph1's CL as needed. You can change the original polygon's shape by going into the graph, and changing S from 1 to 8 (for the preset polygons). You can also go into the Original Polygon folder and edit the coordinates of the original polygon to customize it. After changing a polygon, make sure to click the resetPoints action. Screens 5 - 8: Repeated practice with hidden summary graphs. Change the value in graph1's CL to set the number of problems you want students to complete for it to indicate correct. For rotation and dilation, you can set in the graph1 CL if you want it to only pick (0,0) as a center of rotation/dilation, or to pick a random vertex. Screens 9 - 14: Visualizers for each transformation. The last two screens lets students combine translations, reflections, and rotations. Twitter: @dwekselgreene
