圆锥曲线是高考必考内容,其中圆锥曲线与角度有关的问题,牵涉到直线斜率、三角形相似、解三角形、向量等内容.涉及知识多,综合性强,方法灵活多样,是高考命题的热点和重点,在近几年的高考试题中经常出现。这类问题不仅要求考生具有扎实的基础知识和基本技能,更要有较强的思维能力和分析问题的能力。本文以2015新课标1理科卷第20题为例,谈谈圆锥曲线中解决角相等问题的常用策略。
Conic curve is the college entrance examination will be the content, which cones and angle-related issues, involving the slope of the line, similar to the triangle, the solution of triangles, vectors, etc. Involved in knowledge, comprehensive, flexible and diverse method is the hot topic and Emphasis, in recent years, college entrance examination exams often appear. Such problems not only require candidates to have a solid basic knowledge and basic skills, but also have a strong ability to think and analyze the problem. In this paper, 2015 New Curriculum 1 Science Volume 20, for example, to talk about the conic curve to solve the problem of equal angle commonly used strategies.
