“消点法”是类比代数中求解二元一次方程组的“消元法”而提出的一种解决几何问题的方法.它可以解决这样的一类几何问题:如果这个几何命题的前提条件可以用构图过程表示,这个构图过程的每一步都符合欧几里得作图公法;命题的结论是涉及题中的几何量的一个等式.对于这样的命题我们总可以用消点法一步一步地把所有几何约束化解, The “demerit point method” is a solution to the geometric problem proposed by the “elimination method” for solving a system of linear equations in algebraic algebra. It can solve such a kind of geometric problem: if this geometric proposition The preconditions can be represented by the composition process, each step of which complies with the Euclidean mapping public law; the conclusion of the proposition is an equation involving the geometric quantity of the question. For such a proposition we can always use negative points Law step by step all the geometric constraints resolved,
