为了考查同学们用数学知识解决实际问题的能力,近几年中考数学题中频频出现一种新题型——开放型画图题.这类问题的答案往往不止一个,需多角度进行探索、猜想和论证,才能把所有的符合条件的图形作出来,因而能很好地培养我们的创新思维及动手能力.现以中考题为例,说明这类问题的解法. In order to examine the ability of students to use mathematics knowledge to solve practical problems, in recent years, a new type of question—open type drawing question—has appeared frequently in the mathematics questions of the senior high school entrance examination. The answer to such questions is often more than one, and it requires multiple perspectives to explore and conjecture. With the demonstration, we can make all the eligible graphics, so we can cultivate our innovative thinking and practical ability. Now take the exam questions as an example to illustrate the solution to this type of problem.
