For , if it could meet it in three , those three points would be equally distant from the

**centre**; and hence , there would be three equal straight lines drawn from the same point to the same straight line , which is impossible ( Book 1. Page 45

The

**centre**C , the middle point D , of the chord AB , and the middle point G , of the arc subtended by this chord , are three points of the same line perpendicular to the chord . But two points are sufficient to determine the position ... Page 46

For , if there were a second circumference passing through the three given points A , B , C , its

**centre**could not be out of the line DE , for then it would be unequally distant from A and B ( Book I. Prop . XVI . ) ...### What people are saying - Write a review
