Transfy (Formerly called RotateD)
Transfy Transforms any polygon or line. This program is for
teaching and learning the concepts of polygon transformations.
• Rotations, any degree, counterclockwise, using any point as center of rotation
• Dialations, using any point as center of dilation
• Reflections in any line (you can input anything as y=mx+b)
• Translations, you just enter how far up/down & over.
• Shapes can be a line or up to 9 points.
• Enter shapes in lists L₁ and L₂, avoid tedious entering of coordinates
• Shows Preimage blue and image, red together, with coordinates
• Automatically Adjusts view for best fit to display images of shape
• Compatible with TI84 CE only
