| Abstract: | it is very difficult for the students to solve the distance of a straight line across different surfaces in space solid geometry. The author suggests that the following methods be used to simplify the difficult and complex questions: to make use of the common perpendicular, of both straight lines and surfaces, of surfaces, of extreme values, and of analytic geometry. The methods help students to improve their thinking in images, logical thinking and horizontal thinking. |
