ABCD is a quadrilateral in which a b equal to b c d e f g h are the midpoint of Ab BC CD and ac respectively prove that fgh is a rhombus ABCD is a quadrilateral in which a b equal to b c d e f g h are the midpoint of Ab BC CD and ac respectively prove that fgh is a rhombus bC)-jY Share with your friends Share 0 Neha Sethi answered this Given: ABCD is a quadrilateral in which AD=BC E,F,G and H are the mid points of AB,BD,CD and AC respectively.To show: EFGH is rhombus.Now in △ACD , E and F are the mid points of AB,AC respectively.⇒GH=12AD=12BC ...1 using BPT theoremSimilarly in △ABC,HE=12BC ...2 using BPT theoremNow consider △BCD ,G and F are the mid points of CD and BD respectively GF∥BC and GF=12BC ...3 using BPT theoremand similarly in △ABD,H and E are mid points of AC and AB respectivelyEF=12AD=12BC..4 using BPT theorem and AD=BCFrom 1,2,3 and 4EF=FG=GH=HASince all sides are equal so EFGH is rhombus 0 View Full Answer Harigopal answered this Please find this answer 0
