theorem Th33: :: JORDAN15:33

for n being Nat
for C being Simple_closed_curve
for i, j, k being Nat st 1 < j & j <= k & k < len (Gauge (C,n)) & 1 <= i & i <= width (Gauge (C,n)) & n > 0 & (Gauge (C,n)) * (k,i) in Upper_Arc (L~ (Cage (C,n))) & (Gauge (C,n)) * (j,i) in Lower_Arc (L~ (Cage (C,n))) holds
LSeg (((Gauge (C,n)) * (j,i)),((Gauge (C,n)) * (k,i))) meets Upper_Arc C
