Not long ago, I listened to a subject taught by Qiu Yanping, a discipline leader in Jiangxi Province, who learned the lesson of “Vertical and Parallel”. Vertical and parallel are the two special positions of two straight lines in the same plane. It is based on the students’ understanding of the line and the angle of the teaching content, will be the future students to further understand the rectangular, square, learning parallelogram, triangle And trapezoid, as well as the basis of learning geometry, but also to cultivate the concept of student space carrier.
