Video Summary

Mona wants to draw a figure comprising three segments without lifting her pencil, minimizing the total length drawn. Starting at the edge of a segment is more efficient because she ends up in the center, allowing her to proceed directly to the next segment. Conversely, starting from the center requires backtracking after reaching one end of a segment. By starting at the edge, she only needs to backtrack over the shortest segment. This strategy results in drawing a total of 7 cm: 3 cm, plus 1 cm, plus 1 cm (backtrack), plus 2 cm.
