“相交线与平行线”是“图形与几何”的基本内容.在本章,我们将在已有知识、经验的基础上,继续研究两条直线的位置关系.在本章的学习中,我们不仅要了解补角、余角、对顶角以及它们的性质,也要掌握平行线的特征以及判定直线平行的方法.同时,我们将进一步探索相交与平行的秘密,积累几何活动经验,培养几何直观,进一步发展空间观念,提高推理能力.
“Intersecting Lines and Parallel Lines ” is the basic content of “Graphics and Geometry ” In this chapter, we will continue to study the positional relationship between two lines based on our existing knowledge and experience. , We should not only know the supplementary angle, the complementary angle, the vertex angle and their properties, but also grasp the characteristics of parallel lines and determine the method of straight parallelism.At the same time, we will further explore the secret of intersection and parallelism, accumulate experience of geometric activities, Cultivate the visualization of geometry, further develop the concept of space and improve the ability of reasoning.
