Years ago, the great mathematician Archimedes trisection of an arbitrary angle with compass, ruler, and mark points on the feet, so that mark point to the foot end of the length of the radius is equal to angle; to straightedge movement, so that mark-point arc always on the move, adjust, and when the foot end of the marking points on the feet, and other requirements that have a total of three points simultaneously in ruler now has been online; a total of nine actions to complete.

2400年前，大数学家阿基米德作任意角三等分，用圆规，直尺，且在尺上做记号点，使记号点至尺端的长度等于角圆弧半径；将直尺移动，使记号点始终在圆弧上移动、调整，当尺端、尺上记号点、和其它有要求的一点，共三点同时在直尺的一直线上；共九个动作完成。
