| Abstract: | Finding the parameter in parametric equations of a straight line and taking the advantage of the geometric meaning of the parameter,gave the new proof of the formula of the distance from a certain point to a plane,from a certain point to a straight line,and the distance between skew lines.The new proof method is relatively easy and convenient. |
