OF EUCLID. 79 Nor can two circles touch one another on the outside in Book than one point: for, if it be possible, let the circle ACK <^-ymJtouch the circle ABC in the points A, C, and join AC: there-fore, because the two points A, C are inthe circumference of the circle ACK, thestraight line AC which joins them shallfall within*» the circle ACK: and the cir-cle ACK is without the circle ABC ; andtherefore the straight line AC is withoutthis last circle ; but, because the points A,C are in the circumference of the circleABC, the straight line AC must be wi
