椭圆的焦点三角形常常考查了椭圆定义、三角形中的正余弦定理、内角和定理、面积公式等等,覆盖面广,综合性较强,因此受到了命题者的青睐,特别是面积和张角题型灵活多样,是历年高考的热点,经久不衰。在高考中,是一个重点也是一个难点。近年来,在高考中多是选择题或填空题形式出现,下面,浅谈一下椭圆焦点三角形的若干运用方法,希望对初学者解决此类问题能有所帮助。尤其在高考中,既可以提高准确性,又可以结省时间。 The oval focus triangle often examines the ellipse definition, the sine cosine theorem, the interior angle and the theorem in the triangle, the area formula and so on, the coverage is broad, the synthesis is quite strong, therefore has obtained the propositional favor, especially the area and the angle type Flexible, is the hot college entrance examination over the years, enduring. In the college entrance examination, is a key is a difficult point. In recent years, most of the college entrance examination is a multiple choice or fill in the blank form, the following, a brief talk about some of the use of oval focus triangle, hoping for beginners to solve such problems can be helpful.
