1 Graphic designer to trigger inspiration, exquisite design patterns with
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.
"Repeat" function of the specified range, so that you can do complex designs.
Such as: draw a circle, turn right 12 degrees, forward L length, and then draw a circle, use the repeat function, repeat the previous action 30 times, we can draw a certain point as the center, surrounded by beautiful circular pattern graphics.
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.
Why, turn right 120 degrees instead of 60 degrees? This is the need of students' thinking and learning
