Geometry App
Select h > Geometry to start up the Geometry app. This app allows you to draw and analyze geometric
objects. For example, you can draw a circle and then draw a line that is tangent to a particular point on the
circle.
The Geometry app also includes an animation feature that lets you watch how a figure changes in accordance
with conditions you define.
Note
• Changes to the Angle, Grid, or Axes settings of the Settings menu in the Geometry app, affect only the
Geometry app. They do not affect other apps. Conversely, changes made to these settings in other
apps do not affect the Geometry app.
• The initial default setting of the Geometry app's Angle setting is Degree.
• The examples in this chapter assume Geometry app initial default settings are in use (which are
configured when a new file is created as described under
otherwise noted.
