How to Start and Quit Cabri Jr. on the TI-84 Plus

By C. C. Edwards

Because the TI-84 Plus graphing calculator comes equipped with two geometry applications, Cabri Jr. and GeoMaster, you can now do your geometric investigations on the calculator. Granted, the calculator screen is rather small for some investigations, but other than that, these two calculator applications do almost everything that the computer software packages do.

To start Cabri Jr., press [APPS], use


to move the cursor to the Cabri Jr. application, and press [ENTER]. You are confronted with the first picture. As instructed on the screen, press any key to enter Cabri Jr.


If Cabri Jr. is one of the first ten applications in your APPS menu, you can start the application be pressing [APPS] and keying in the number to the left of Cabri Jr. in the APPS menu.

After starting Cabri Jr., the F1 menu (or your work from the last time you used this application) appears on the screen. The F1 menu appears only when the calculator has never before used Cabri Jr., or when you started a new file the last time you used the calculator but exited the application before creating that new file. If you see the F1 menu, press


to start a new file.

After a few moments of inactivity, Cabri Jr. displays a help screen, as illustrated in the third picture. Press [ENTER] to get rid of the help screen so that you can continue with your work.

To quit Cabri Jr., press [2nd][MODE] or select Quit from the F1 menu by pressing [Y=][8]. The next time you start Cabri Jr., your work will appear on the screen as you left it.

When the calculator remains idle for about five minutes, it shuts itself off in order to extend the life of its batteries. If this happens while you are using the Cabri Jr. application, it also quits this application.

So when you turn the calculator back on, you will have to go to the APPS menu to restart Cabri Jr. But don’t worry, after restarting Cabri Jr., your work will appear on the screen as it was before the calculator powered down.
