圆心O的内接六边形ABCDEF中,AB=CD=EF,
已知,六边形ABCDEF的各边都和⊙O相切求证:AB+CD+EF=BC+DE+FA
在六边形abcdef中ab‖de bc‖ef cd‖af bc-ef = af-cd>0证明六边形abcdef各角相等
如图,在六边形ABCDEF中,AB‖ED,AF‖CD,BC‖EF,AB=ED,AF=CD,BC=EF,又知对角线
六边形ABCDEF中,AB//DE,BC//EF,CD//AF,对边之差EF-BC=AB-DE=CD-AF>0,求证:该
如,六边形ABCDEF中,AB∥DE,BC∥EF,CD∥AF,对边之差BC-EF=ED-AB=AF-CD>0,求证;:六
如图所示的六边形ABCDEF中,所有角相等. 问:若AB=3 BC=4 CD=2 DE=3,试求六边形ABCDEF的周长
如图,在六边形ABCDEF中,AB=DE,CD=AF,BF=CE且AF//CD求证BC=EF
如图.在六边形ABCDEF中,AB平行DE,BC平行EF,AF平行CD,若∠B=80°,∠C=130°
如图在六边形ABCDEF中,AF‖CD,AB‖DE,BC‖EF,且∠A=120,∠B=100
如图,在六边形ABCDEF中,AF//CD,AB//DE,BC//EF,A=120°,∠B=80°,
如图,在六边形ABCDEF中,AB//DE,BC//EF,AF//CD,若角B=80度,角C=130度,求角A
如图,在六边形ABCDEF中,AF平行于CD,AB平行于DE,BC平行于EF,角A=120度,度B=80度
