1. Defining the contents and requirements of the college entrance examination. The three-dimensional geometry is divided into two sections: “straight and plane”, “polyhedron and rotating body”. The “exam description” issued by the National Board of Education Examination Center clearly stipulates the content and requirements of the examination. .1. For the contents of the “Linear and Plane” chapter of the exam: Basic properties of planes and planes. Drawings of diagrammatic drawings. Positional relationship between two lines. Two lines parallel to the same line are parallel to each other. The parallel angle. The angle formed by the straight lines of different sides. The concept of two straight lines perpendicular to each other. The perpendicular lines and distances of straight lines on different sides. The positional relationship between straight lines and planes. The judgment and nature of parallel lines and planes. The judgment and nature of the plane perpendicularity. The distance from the point to the plane. The projection of the oblique line on the plane. The angle formed by the straight line and the plane. The triple vertical line theorem and its inverse theorem.
