The many useful Geometric Graphing Functions allow you to draw and analyze geometric figures efficiently. As shown in the above examples, the students can learn the general theorem by drawing the figures, and they can confirm that the theorem still holds true even when they deform the triangle. The Animation function enables you to move the drawn geometric figures. With this function, the students can learn visually, for example, how the figure changes when the angles and the values of the coordinates are changed. By dragging and dropping a geometric figure to the main application window, you can obtain the numerical data for the figure. And by dragging and dropping the numerical data to the Geometry window, the data can be reflected in the figure. Drag & Drop geometric figure Drag & Drop numerical data The Geometry Link Function enables you to dynamically link the eActivity data and the Geometry window data. Define the Geometry Link row on the eActivity file. Drag & Drop a side of the geometric figure to the Geometry Link row. Change the data of a side of the geometric figure to any of the formulas you want to specify. When your specified formula is determined, the geometric figure changes in conjunction with the changes made.
