It does not seem possible that such circles exist, unless the diagonals of the tangential quadrilateral are perpendicular to each other, i.e., unless is at least a kite, or unless at least two of the circles (or) coincide with the quadrilateral incircle.
Hindi ito tila posible na tulad ng bilog na umiiral, maliban kung ang diagonals ng tanghential may apat na gilid ay tirik sa bawat isa, ibig sabihin, maliban na lamang kung ay hindi bababa sa isang saranggola, o maliban na lamang kung hindi bababa sa dalawang ng bilog (o) Magkataon sa may apat na gilid incircle.
