研习2015年全国各地中考数学卷,常常为有些试题的精巧构思、苦心经营而感动.比如2015年江苏无锡卷第26题没有图形,但是求解时却对几何图形中的线段、线段中点、角平分线、平行四边形(包括菱形)、圆、直角三角形、轴对称等知识全面覆盖,是一道不可多得的好题,下面为同学们讲解该题,希望同学们有所收获. Studying 2015 mathematics test in all parts of the country, often for some of the delicate ideas of the project, painstakingly moved.For example, in 2015 Wuxi Volume 26 questions no graphics, but the solution is geometric line segments, line midpoint, angle Bisection lines, parallelogram (including diamond), circle, right triangle, axis symmetry and other knowledge comprehensive coverage is a rare good topic, the following for the students to explain the problem, I hope the students have benefited.
