Boolean values

Jump to: navigation, search


You can use the Boolean variables true and false in GeoGebra. Just type, for example, a = true or b = false into the Input Bar and press the Enter-key.

Check Box and Arrow Keys

Free Boolean variables can be displayed as check boxes in the Menu view graphics.svg Graphics View (see tool Mode showcheckbox.svgCheck Box Tool). After selecting a Boolean variable in the Menu view algebra.svg Algebra View you can use the arrow keys to change the value of the Boolean variable (see Manual Animation).

Note: You may also use Boolean variables like numbers (value 0 or 1). This allows you to use a checkbox as the dynamic speed of an animated slider allowing you to start and stop the animation. In this case, the animation button is only shown in the Menu view graphics.svg Graphics View if there is also an animated slider with static (i.e. non-dynamic) speed.

Operations

You can use the following operations for Boolean variables and conditions in GeoGebra by either selecting them from the list next to the Input Bar or by entering them using the keyboard:
