Rotations about a point & origin using Geometer's Sketchpad

Our Task:

Plot and label any shape on a coordinate plane using either Geometer's Sketchpad or regular graph paper.

Rotate the shape about a fixed point any number of degrees clockwise or counterclockwise.  Plot & label its new coordinates.

Rotate the shape about the origin (0,0) any number of degrees clockwise or counterclockwise.  Plot & label its new coordinates.
