考点解读直线和平面点击考点一直线、平面的平行和垂直关系直线和平面平行的判定和性质可简述为“线线平行!线面平行”,直线和平面垂直的判定和性质集中反映了线线垂直与线面垂直、面面垂直的关系.直线和平面的平行与垂直是两种非常重要的关系,二者的综合与联系,更是线面关系的精髓.
The interpretation of the test site on the straight lines and planes. The determination of the straight line and the parallel and perpendicular relationship of the plane and the parallelism of the plane can be described briefly as “line parallelism, line plane parallelism”. The determination of the vertical and horizontal planes and the nature of the plane focus on the line. Vertical and vertical lines, perpendicular to the surface of the relationship between the vertical and horizontal lines and planes are two very important relations, the synthesis and contact between the two, but also the essence of the relationship between lines.
