How to Apply the Principle of Projection Transformation to Deduce the Segment’s Real Length in the Right-Angled Triangle

Article Preview

Abstract:

The problems of measurement such as real length and real shape are often met in solving practical engineering problems.The method of changing plane which is used to simplify the problem is researched how to change the relative position of the geometric elements relative to the projective plane in the space. In practical applications,we need to use the method of projection to solve the real length of oblique line and the angle between the oblique line and projective plane.
