Geometry Explorer Help

Using the Misc Menu:

(Back To Help Home)

The items in the menu labeled "Misc" handle actions that are not easily characterized into a group.  The items listed under this menu will change depending on which of the three possible geometries you are working in -- Euclidean, Hyperbolic, or Elliptic.
 

Euclidean:

Show/Hide Objects:
Choose this option to create a button that will control the visibility of the current set of selected objects.  The button is created with the objects visible, and each time the user clicks the button, the objects will change their visibility.
Move Objects
Choose this option to create a button that will move points toward other points.  For every pair of points that are selected, if the user clicks the Move button, the first point in the pair will move towards the second point.  Thus, if four points A,B,C, and D are selected, in that order, and a Move button is created, then when the user clicks the Move button, point A will move to B's position and point C will move to point D's position.
Animate Objects:
Choose this option to create a button that will control the animation of all currently selected objects.  Once this option is selected, the properties dialog will popup where animation properties can be set (e.g., speed).  After the button is created, when the user clicks the Animate button, the animation starts and when the user clicks the button a second time the animation stops.  For more information on animating objects, look here.
Iterate Function:
Choose this option to create a button that will carry out the iteration of a function y=f(x) on a point. To enable this menu option, select the graph of a function y=f(x).  Once this option is selected, the Iterate button will be created on the screen. To use this button, first select a point and then click the button.  Geometry Explorer will take the x-value of the point and find a point on the graph and another point that lies on the line y=x, which can be used for the next iterate.  For example, in the figure, we have created an Iterate button for the parabola. Then, we selected point A and clicked the Iterate button. The system creates all of the objects in red: point B on the graph, using the x-value of A, point C on y=x, using the y-value of B, and the two segments AB and BC. If we now select C and click iterate, we will  get a new point which is essentially f(f(x)) for x the x-value of point A. 
Iterate
Sequence Buttons:
Choose this option to create a button that will carry out the actions of a set of existing buttons that are currently selected.

Hyperbolic:
HyperTriangle
Control Buttons: The control buttons have the same functionality as in the Euclidean case, except for the Iterate button, which is not available in Hyperbolic geometry.  Look above for info on Control Buttons.

Elliptic:
Control Buttons: The control buttons have the same functionality as in the Euclidean case, except for the Iterate button, which is not available in Elliptic geometry.  Look above for info on Control Buttons.
