You need to do
the first two activities listed here, then you may make some
choices. When there are directions, please read them before asking
me "what do I do?"
Geometry and
Measurement
Angles and
Polygons
Start Here:
When you have
mastered the angle estimates, work on what regular polygons are:
You may now go
to Geo-Logo and try making regular polygons using moves and turns.
See if you can figure out how to make a regular pentagon
(difficult), hexagon, or "any-ogon of your choice.
Other
challenges include:
Create a
polygon with set xy or moves and turns, then try to create its
mirror image in another quadrant (line symmetry)
If you are
still struggling with the triangle names and properties, go here
This applet lets you explore the angle sums of different
polygons, you can add to your table to find a pattern:
