WA = WN    --->  call this length "a"

LA = LK       --->  call this length "b"

KR = RO     --->  call this length "c"

OU = UN     --->  call this length "d"

 

WL  =  a + b  =  12                     WL + RU  =  a + b + c + d  =  34

LR  =  b + c  =  18                                                 b + c        =  18                                (subtracting)

RU  =  c + d  =  22                                           -------------------------

UW  =  a + d  =  ?                                           a              + d  =  16

 

Will it always be the case that a quadrilateral that is curcumsribed around a circle will have sides such that

one pair of opposite sides will have the same total length as the other pair of opposite sides?
