+23248 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?
