Straight Line Circle Theory 

 

Straight Line Circle Theory states that the reason a line ought not be used inside the circle for radius is because a line is straight and has square edges and the arc of a circle is round. Thus, when the radius of a circle is measured as a line in the center of the circle, the line does not sit flush against the arc of a circle. Because the line does not sit flush against the arc of the circle the radius cannot be accurately measured.   Therefore, in theory a line in the center of a circle cannot accurately measure the radius of a circle.
