内容摘要 如果利用π来完成圆化方尺规作图是不可能的，主要原因是代数式方

Summary If you use π to complete the circle of feet and compasses is impossible, mainly due to an insufficient number of algebraic equations; however, listed according to the equivalent relationship rounded square patterned algebraic equations for π is sufficient. In other words, rounded square composition provides problem-solving ideas to solve the Ruler of π. So, rounded side can not only Ruler, the best idea is to solve the Ruler of pi -π. <br>Keywords rounded square; Ruler of π; three plane geometry problem. <br>MR2010 Categories:

Abstract If it is not possible to use argon to complete the roundsquare ruler graph, the main reason is that the number of algebraic equations is not enough; In other words, the composition of the rounded square provides an understanding of the problem to solve the problem of the scale diagram of the crucible. Therefore, the rounding square can not only be a ruler chart, but also to solve the circumference rate - the best way of thinking of the ruler diagram.<br>Keywords Roundsquare; the scale of the plan; the three major problems of flat geometry.<br>MR2010 topic classification:

It is impossible to use π to complete the construction of the circular ruler, the main reason is that the number of algebraic equation is not enough; however, it is enough to list the algebraic equation about π according to the equivalent relation of the composition of the circular square. That is to say, the composition of the rounded square provides a solution to the problem of π's ruler drawing. Therefore, the rounded square is not only the best way to draw with ruler, but also the best way to solve the problem of drawing with ruler with PI.<br>Key words: rounded square; π ruler drawing; three problems of plane geometry.<br>Mr2010 topic classification:<br>
