Tangents to Circles. Graphic Math Graphing Equations. EGA or VGA recommended, mouse optional.
Students use constructions to explore geometric shapes and properties.
Students can study and make conjectures about geometric shapes without having to draw them. The software includes a full complement of transformations including translation, rotation, reflection and inversions. A function feature allows the user to define any set of constructions that may then be executed on a given shape. Libraries of functions can be developed and saved. A teacher's manual includes a tutorial, a description of each menu, teaching suggestions and some suggested units.
