36、，AQABBQ595165.综上所述，若得到AQP和四边形BCPQ，则 0AQ165，所以符合条件的AQ的长有 3，2，53，一共有3 个13解：(1)证明：在?ABCD中，ADBC，DFBE.DFBE，四边形DBEF为平行四边形，BDEF.(2)DFBE，DFGCEG，DGGCDFEC23.DFBE4，EC 6.14证明：A是CD的中点，ACAD，ACAD，BACD.又CAEBAC，CAEBAC，ACABAEAC，AC2ABAE.又ACAD，ACADABAE.15证明：(1)A36，C72，精品w o r d 学习资料 可编辑资料-精心整理-欢迎下载-第 6 页，共 6 页文档编码:CE9I
