You can completely specify a circle in a plane by giving the coordinates of its center point, and the length of the radius.
The properties associated with the angles of a circle is the amount of rotation about the point of intersection of two lines in order to make one line into correspondence with the other. The arc of a circle consists of two points on the circle and all of the points on the circle lie between those two points.

A chordof a circle is a geometric line segment whose endpoints both lie on the circle. A secantor a secant line is the line extension of a chord. More generally, a chord is a line segment joining two points on any curve, such as but not limited to an ellipse. A chord that passes through the circle's center point is the circle's diameter.

There cannot be such a postulate because it is not true. Consider a line segment AB and let C be any point on the line between A and B. If the three points are A, B and C, there can be no circle that goes through them. It is so easy to show that the postulate is false that no mathematician would want his (they were mostly male) name associated with such nonsense. Well, if one of the points approach the line that goes through the other two points, the radius of the circle diverges. The line is the limit of the ever-growing circles. In the ordinary plane, the limit itself does not exist as a circle, but mathematicians have supplemented the plane with infinity to "hold" the centres of such "straight" circles.
