He argued that if a focus of a conic section were allowed to move along the line joining the foci, the geometric form would morph or degenerate, one into another.
他主张到,如果一个圆锥截面的焦点可以沿着连接焦点的线运动,那么这个几何形状会把一个焦点改变或退化成另外一个。
if the sides of a polygon pass through fixed points and all but one of the vertices lie on fixed lines, then the remaining vertices describe a conic section or a straight line.
