reserve a, b, c, d, r, s for Real,
  n for Element of NAT,
  p, p1, p2 for Point of TOP-REAL 2,
  x, y for Point of TOP-REAL n,
  C for Simple_closed_curve,
  A, B, P for Subset of TOP-REAL 2,
  U, V for Subset of (TOP-REAL 2)|C`,

theorem Th14:
  A is_inside_component_of B implies UBD B misses A
proof
  assume A is_inside_component_of B;
  then A c= BDD B by JORDAN2C:22;
  hence thesis by JORDAN2C:24,XBOOLE_1:63;
