This program uses the design of the "relative position", when you delete a command, the following command will still be performed, so it will produce unpredictable graphics.

Such as: a continuous drawn a few lines, the last circle. You delete the last one drawing a line command, the last line disappear, then directly draw a circle, so it will produce another style of graphics.

XY axis position and length, the precise angle control, so that you can use this program as a simple version of the CAD programs.

2 Parents or teachers to teach geometry

Such as: draw a line the length L of the straight line, turn right 120 degrees, and then draw a line of length L a straight line, turn right 120 degrees, and then draw a line of length L a straight line, so they can draw a triangle.
