几何直观是《义务教育数学课程标准(2011年版)》的新增关键词,它主要是指利用图形描述和分析问题.笔者在教学实践中了解到,学生对利用图形描述和分析问题的意识还没有得到有效的引导.下面,笔者结合一个具体的实例,谈谈几何直观在解决数学问题中的应用,以期抛砖引玉.原题呈现(1)如图1,△ABC中,∠ABC与∠ACB Geometry intuition is the new key word of Compulsory Education Mathematics Curriculum Standard (2011 Edition), which mainly refers to the use of graphics to describe and analyze the problem.The author understands in the teaching practice that the students’ awareness of using the graph description and analysis problems Did not get an effective guide below, I combine a concrete example, talk about geometric intuition in the application of solving mathematical problems, with a view to throwing bricks and stones. (1) As shown in Figure 1, △ ABC, ∠ ABC and ∠ ACB
