- 线段及直线的基本运算 1. 点与线段的关系2. 求点到线段所在直线垂线的垂足3. 点到线段的最近点4. 点到线段所在直线的距离 5. 点到折线集的最近距离 6. 判断圆是否在多边形内7. 求矢量夹角余弦 8. 求线段之间的夹角9. 判断线段是否相交10.判断线段是否相交但不交在端点处11.求线段所在直线的方程 12.求直线的斜率 13.求直线的倾斜角14.求点关于某直线的对称点15.判断两条直线是否相交及求直线交点 16.判断线段是否相交，如果相交返回交点-straight line segme
LineAndIntersection
- 求解double值的前去后继，并且通过double值求解两条直线的交点，计算机中的直线交点可能不止一个，通过本程序能够求出交点，然后将直线和交点显示出来-We know the lines in the computer can have more than one intersections, so this program shows the lines and the intersectioins
Intersection
- 程序可以求出两条直线的所有交点，进行放大或缩小显示以及标记出交点。-Find all the intersection points of two lines and zoom the lines.

- 已知两条直线上两点的坐标，求这两条直线他们的交点。-The known two lines of two coordinates, to work the intersection of two straight lines they.

LineLine2Point
- 此程序是空间两条直线求交点，需要知道直线上两个点就可以！- two space straight lines to find intersection, which need to know two points on the line!
