we 're going to use geomter's sketch pad, which allows you to construct things, but then also to change your construction within certain parameter.
a section on parallel lines and a section on circles and those two pieces are sort of historically important pieces in mathematics, in the development of geometry.
we used geometer's sketch pad, which is a very nice piece of geometry software.
the geometry we learned in school isn't the only geometry.
oh, perfect a 90-degree angle.
in order to use a standard data from across all three-dimensional polygons, we had to begin with triangles.
people don't realize how precise mathematical language is and how imprecise...english is.
welcome back.
some things that we've seen before.
so we 're going to revisit this idea of construction that we saw with patty paper, and what does it mean to construct something versus drawing something.
at that time you were restricting yourself to the tools of folding paper and drawing on the paper.
we now have a computer tool.
