Creating Shapes Using Gestures (MathDraw)
The MathDraw tool lets you use touchscreen gestures to create points, lines, circles,
and other shapes.
• MathDraw is available in Geometry and Graphing.
• Graphing view when the x scale and y scale are identical. This avoids non-circular
ellipses and non-square rectangles appearing as circles and squares.
Note: MathDraw is not available in the 3D Graphing.
Activating MathDraw
1. Tap Add, and then tap .
2. Tap Tools .
3. Tap Actions menu, select MathDraw.
The MathDraw tool appears in the application Toolbar. You can begin
using the tool.
Canceling MathDraw
▶ When you have finished using the MathDraw tool, tap the X on the tool.
Creating Points
To create a labeled point, tap in an open area.
• If the point is close to an existing line, segment, ray, geometric conic (including
circles), or polygon, the point snaps to that object. You can also place a point on the
intersection of any two of those types of objects.
• If the point is close to a visible grid location in a Graphs view or Geometry view, it
snaps to the grid.
Drawing Lines and Segments
To create a line or segment, touch the initial position, and then drag to the end
position.
• If the drawn line passes near an existing point, the line snaps to the point.
• If the drawn line starts close to an existing point and ends next to another existing
point , it becomes a segment defined by those points.
• If the drawn line is nearly parallel or perpendicular to an existing line, segment, or
side of a polygon, it aligns to that object.
