Chapter 8:
Geometry Application
The Geometry application allows you to draw and analyze geometric figures.
For example, you can draw a circle and then draw a line that is tangent to
a particular point on the circle. The Geometry application also includes an
animation feature that lets you watch how a figure changes in accordance with
conditions you define.
Starting up the Geometry application displays a large white Geometry window.
Use this window to draw the figures you want. If you left figures on the
Geometry window the last time you exited the Geometry application, those
figures will appear the next time you start it up.
