Tool name 3: Geometry Trace 4: Erase Geometry Trace Tool function Enables you to view the pathway of a geometric or analytic object (such as a function graph) on the work area. The pathway has a delayed fade. As more movement occurs on the work area, older portions of the pathway fade. If you temporarily halt movement, a portion of the trace path remains displayed. Halts geometric trace and erases all persistent pathways on the work area. Points and Lines Menu Tools Tool name Tool function Press: 1: Point Constructs a point defined in free space, on an object, or at the intersection of two objects. b61 2: Point On Constructs a point defined on an b62 object. When the object is a function graph, the coordinates are displayed. 3: Intersection Constructs a point at each b63 Point intersection of two selected objects. 4: Line Constructs an infinite line defined by b64 two points or by a point and a direction. If you press g while creating the line, you limit its orientation, relative to the x-axis or the horizontal aspect of the screen, by 15- increments. 5: Segment Constructs a segment, defined by two end points, which may be b65 created or defined in free space or on a defined object. If you press g while creating the segment, you limit its orientation, relative to the x-axis or the horizontal aspect of the screen, by 15- increments. Using Graphs & Geometry 75
