| The space in the solid geometry graph is various, so how do we understand and grasp them? General methods are to break it down and from the part of it to solve. Space is a three-dimensional graphics, in order to clearly understand their relationship with their respective properties, we must start from the elements, to get to know all kinds of graphics in the space. From the whole to the part or from the part to the whole, students can gradually understand the properties of the space geometry. Parallel and vertical relations are one of the typical and common relations between the two class position. In our daily life, point, line, surface, their positional relationship are widely used, so we need to learn to distinguish between them. and the judgement and determination of Parallel and perpendicular have always been a part of the test of entrance to the college, from which the importance of space geometry is shown, as for the learning of this section, students should be based on the unique three-dimensional geometry of space, which requires a full understanding of the concept of spatial imagination, and the ability of analzying and logical thought, so a series of questions are arised when students study this part, such as the failure of imagination of graphics, the conceptual confusion, and the wrong use of the theories, and the lack of logical thought, and the proper use of language.while this paper analyzes the relationship of line to line, line and surface and surface and surface between the parallel and perpendicular based on the nature of theories and distinctions. as fully understand the present teaching situation, Analysis of the students in this part of the learning process the problems and find solutions to solve problems, and finally use a lot of the classic examples of the tests of entrance to college, which aims to training students’spatial imagination, logical thought ability under the premise of abstract thinking ability, problem-solving skills. |
