Poly allows the user to view and interact with polyhedra and
their nets, thus connecting two and three dimensional
geometries. Exploring The Software: - Begin by going to the File
menu and opening "Preferences". I suggest you check "3-D
Shaded", "3-D Edges", and "2-D Net" views. - Start with one of
the Platonic Solids. Select the 3-D shaded view. To explore one
of the interactive options, try a demonstration routine under
View > "Start Demo". You can control this action with a
click-&-drag on the slider, or have the slider move
automatically with a grab-drag-&-release action. - Another
interactive option is to grab-&-drag the figure in the viewing
field, or use a grab-drag-&-release action to put it into
motion. - You can use the View > "Printer" to set up what you'd
want to have printed on a handout. - You can get information
about the polyhedra categories in the Help menu. Thinking About
the Mathematics: - A net is an arrangement of connected polygons
that become faces when the two dimensional net is folded
