Reproduce this drawing (Posted on 2005-11-25) Difficulty: 2 of 5
What is the minimum number of strokes to reproduce the drawing below without lifting up the pencil from the paper (no tricks at all), and without passing over a line segment (or part of it) already drawn? You may begin and end wherever you like, and line segments may cross each other, but only as intersections.

Note: a new stroke occurs when a line type ceased because you have to stop and change direction.

You say "B to C isnīt a stroke, itīs a line. Only when you change direction, occurs a stroke. (Read again the note about what is a stroke.) "

Reading that note, it says "a new stroke occurs when a line type ceased because you have to stop and change direction" (my emphasis).  If there's to be a new stroke there must have been an old stroke.  As for the difference between a stroke and a line, every line is at least one stroke, and no one's quibbling that, for example, NB is a line, and therefore can't be a stroke.
