高考题来源于课本而又高于课本,对课本习题的研究可以促进对高考试题的理解和解答.与角相关的数学知识点有向量、三角恒等变换、三角函数、三角形面积公式等,在求角的问题中,可以借助这些数学知识点来进行解决.几何画板具有动态演示和探索角度大小的功能,在求角的大小的过程中,将直观感受所得到的角度利用几何画板进行探究,可以给证明提供一定的思路借鉴和方法指导.将课本中的重要习题和相关高考题进行关联性研究,能够形成对一类问题解决的一般方法.
The college entrance examination questions come from the textbook but higher than the textbook.The research on the textbook exercises can promote the understanding and solution to the college entrance examination questions.And angle related mathematics knowledge points have vectors, trigonometric identity transformation, trigonometric function, triangle area formula, The problem of seeking angle can be solved by means of these mathematical knowledge points.Geometry drawing board has the function of dynamic demonstration and exploration of angle size.Under the process of seeking the angle, Can provide evidence to prove some ways to learn from and guidance.Classification of the textbooks and related issues related to college entrance examination, can form a general solution to a problem.
