在学习之余,我发现与点、线、面的位置关系有关命题真假的辨别及异面直线所成的角的试题是每年高考考查的重点。比如2016年课标卷Ⅰ的文科第11题,就考查了异面直线所成的角,并且该题可以从“平移”与“补形法”两个角度去思考解答,而“平移”与“补形法”则是我们解决异面直线所成角的两个重要手段。在点、线、面的位置关系这一部分,我们应当高度重视求异面直线所成的角这一题型,切实掌握求异面直线所成角的
Apart from learning, I found that the positional relationship between points, lines, and faces is related to the identification of true and false propositions, and the examination of the angles formed by different straight lines is the focus of the annual college entrance examination. For example, in the 11th question of the 2016 liberal arts curriculum I, we examine the angle formed by a straight line from the opposite side, and this question can be answered from two perspectives: the “translation” and the “complementary method.” “Translate” and “Complement method” are two important means to solve the angles formed by the lines on the opposite sides. In the part of the positional relationship between points, lines, and surfaces, we should attach great importance to the question of the angle formed by the straight lines of different sides, and earnestly grasp the angles formed by seeking straight lines on different sides.
