近几年各地高考与高考模拟试题中频频出现“折线距离”(即曼哈顿距离)相关问题,如2014年高考数学福建卷(文科)第12题.这类问题题型新颖,因而备受命题者的青睐.本文对“折线距离”问题进行归类剖析,并探究其解题策略.一、“折线距离”的几何图形问题例1(2014年福建高考题)在平面直角
In recent years, problems related to “distance line distance” (that is, Manhattan distance) have frequently appeared in the college entrance examination and college entrance examination simulation test questions, such as the 2014 college entrance examination mathematics Fujian volumes (Liberal Arts) item 12. These types of questions are novel and therefore much appreciated. Propositioners’ favor. This paper classifies and analyzes the problem of “distance between lines” and explores its strategy for solving problems. 1. Geometrical problem of “line break distance” Example 1 (2014 Fujian College Entrance Exam) is at right angles to the plane
