Introduction to Geometric Objects
Geometry tools are accessible in both the Graphs and Geometry applications. You can
use these tools to draw and investigate objects such as points, lines, and shapes.
• The Graphing view shows the Graphs work area superimposed on the Geometry
work area. You can select, measure, and alter objects in both work areas.
• The Plane Geometry view shows only the objects created in the Geometry
application.
Objects Created in the Graphs Application
Points, lines, and shapes created in the Graphs application are analytic objects.
• All points that define these objects reside on the x,y graph plane. Objects created
here are visible only in the Graphs application. Changing the axes scale affects the
appearance of the objects.
• You can display and edit the coordinates of any point on an object.
• You can display the equation of a line, tangent line, circle shape, or geometric conic
created in the Graphs application.
