Naming a point You can name points and vertices in either the Graphing or Plane Geometry view. Because they are not tied to a specific coordinate, names remain unchanged if you alter the location of any portion of an object. 1. Right-click the item to display its context menu, and select Label. Handheld: Hover over the point, press / b, and select Label. 2. Type the name for the point in the text box. (Optional) You can name a point as you create it by typing a letter or name immediately after you define the point. For example, when creating a triangle, type the letter "x" after creating the first vertex. Type "y" and "z"for the remaining two vertices as you create them. Redefining a point You can redefine a point from a point on the work area to an object, from one object to another, or from the analytic window to the Plane Geometry View work area (or from the geometric work area to the analytic window). 1. Create a point, or decide which existing point you want to redefine. 2. From the Actions menu, select the Redefine tool. 3. Click the point you want to redefine, then click the object or work area at the location for the redefinition. The point moves to the object or new location. Graphs & Geometry 503
