Geometry 149

Note

Calculations referencing geometry variables can be made in

the CAS or in the Numeric view of the Geometry app

(explained below on page 150).

You can change the definition of an object by selecting it,

tapping , and altering one or more of its defining

parameters. The object is modified accordingly in Plot view.

For example, if you selected point GB in the illustration above,

tapped , changed one or both of the point’s

coordinates, and tapped , you would find, on returning

to Plot view, a circle of a different size.

Creating objects You can also create an object in Symbolic view. Tap ,

define the object—for example, point(4,6)—and press

E. The object is created and can be seen in Plot view.

Another example: to draw aline through points P and Q, enter

line(GP,GQ) in Symbolic view and press

E. When

you return to Plot view, you will see a line passing through

points P and Q.

The object-creation

commands available in

Symbolic view can be seen

by tapping . The

syntax for each command is

given in “Geometry

functions and commands”

on page 165.

Re-ordering

entries

You can re-order the entries in Symbolic view. Objects are

drawn in Plot view in the order in which they are defined in

Symbolic view. To change the position of an entry, highlight it

and tap either (to move it down the list) or (to

move it up).

Hiding an object To prevent an object displaying in Plot view, deselect it in

Symbolic view:

1. Highlight the item to be hidden.

2. Tap .

Repeat the procedure to make the object visible again.
