[color=#c51414][b]G[/b]eneral [b]E[/b]ducational [b]D[/b]evelopment[/color] (GED) tests are a group of four subject tests which, when passed, certify that the test taker has American or Canadian high school-level academic skills. Here are some topics which can assist students in learning the mathematics covered on the GED/HiSET/TASC/GCSE [color=#c51414][b]G[/b]eneral [b]C[/b]ertificate of [b]S[/b]econdary [b]E[/b]ducation[/color]. Book 1 is a compilation of basic skills needed for success, but not tested. [b]Mostly PreGED Skills[/b] Book 2 has many activities which are tested.

1.1.

Full Circle Protractors

1) Standard Radian Measures based on fractional parts of π. (StdRads)[br]2) Degree Measures based on the degree equivalents of above. (DegMks)[br]3) Decimal Radian Measures where 1 radian = 57.296° (DecRads)[br][br]Check Boxes for 1 & 2 can be both checked as the correlate well. The DecRads check box is best displayed alone.
There is a classroom radian student protractor called the [url=http://www.proradian.net/]ProRadian[\url]; there is a Unrolling a Circle video available. Thanks, Jennifer Silverman jen@proradian.net
Why is a Circle 360 Degrees, Why Not a Simpler Number, like 100?
