怎样学习平行四边形及特殊平行四边形?根据新课程改革的理念要求,笔者认为:教者要精选习题,认真钻研教材,学者要精做习题,融会贯通.下面就以一道典型的几何题为例,加深对平行四边形和特殊平行四边形的理解与识别.题目:已知:如图,以△ABC的三边为边在BC的同侧分别作三个等边三角 How to study parallelograms and special parallelograms? According to the requirements of the new curriculum reform, the author believes that: the teacher must select exercises, study materials carefully, and scholars must do exercises carefully. The following will take a typical geometric problem as an example. Deepen the understanding and recognition of parallelograms and special parallelograms. Title: Known: As shown in the figure, three sides of △ABC are used as the sides of BC to make three equilateral triangles respectively.
