是我的一个新的PROJECT,没时间做了,好的我再加20分
所以我没时间看了，起码要1页把，当然1页50分太少了，我自己来写，不过还是谢谢你AXIONGPERSON。

一个四边形能够被一个圆所包围叫做循环四边形 （意思就是四边形的四个点都在一个圆上） 以下哪个一定是循环四边形：parallelograms kites（本人能力有限 这个解释不好 暂时为 平行四边形） 等腰梯形 菱形 长方形 或者 正方形 ? 哪个一定不循环 ?并解释原因
只要四边形对角相加等于180度就一定在一个圆上 所以 等腰梯形 长方形 正方形 一定在一个圆上
而 菱形 对角相加不相等180度（等于180度的话就是正方形了） 所以不在圆上
平行四边形包括矩形 正方形 因此这个无法判定的
答案仅供参考 因为是我自己翻译自己做的 不是很肯定

可以与圆形内切的四边形也叫旋转四边形. 下列哪一种四边形在任何情况下总是可以与圆内切，而哪一种不能，并解释原因：平行四边行，等腰梯形，菱形，矩行，和正方形。

答案是菱形~~rhombuses
