IViewing the Measurements of a Figure

The type of information that appears in the measurement box depends on the figure that is currently selected on the display. If a line segment is selected, for example, the measurement box shows the distance, slope, angle from the x-axis, and the equation for that line. You can specify the type of information you want to view by tapping the down arrow button to the left of the measurement box, and then tapping the appropriate icon on the icon palette that appears.

The following table describes the information that appears when you tap each icon, and explains when each icon is available for selection.
