From sim triangles BC/GJ = EB/AG & EB/EA = AG/AB

ReplyDelete=> BC/GJ = EA/AB

NOte that Triangles ABE and EHC are similar ( case AA)

ReplyDeleteso AB/AE=FH/BC => AB.BC=AE.FH

and area (ABCD)= area(FHJG)

AB=s, EB=a, EF=a', FH= s'

ReplyDeleteEA=d=sqrt(s²+a²)=FG

a':a= s:d => a'=as/d

s':a'=s:a => s'=s/a*as/d=s²/d

=> FH*FG=s'*d = s²
