A circle as such does not have a start point nor an end point. We do however have to start at one point and end at the same point when we draw a perfect circle, but after it is drawn, the actual circle does not have a start nor an end. We might be able to see where we started and ended but this is of no significance to the actual start/end point of the circle as the circle itself does not have any.
it's what you call circle
The radius
A segment with end points on a circle is a chord.
A chord
Radius
An oval is used for an endpoint (Start/End/Return). A circle is used as a connector, for instance, if you get to a point where to want to run a subroutine, put a circle connector with a label (a letter, for instance). At the beginning of that subroutine, start it with the same lettered circle connector.
The center of a circle is called the origin. It is a point at one end of a radius, the other end of which defines the circumference of the circle.
You see every circle is really a different object you must remember in that drawing one circle is not the same thing as drawing another circle both are separated by space and time which proves they are different Objects.And so a circle begins where you first draw the line and ends where you last draw the line which happens to be usually around about the same point, and so a circle has no definite begin as every circle has its own beginning, a circles beginning and end are the same point and all the rest of points and the line which develops the loop to create the circle is the middle, so it really depends on where you first draw it, and it must have a beginning or else the circle would never have been drawn and it must have an end or else it would not form to create a circle, thus a circle must have a start and end, and they must be the same point and they must be the point in which you first and/or last draw them.Where ever you want it to , like another 2-D shape.
circle, but the given end point is called the center of a circle : )
Circle.
A full circle has no end. It is continuous.It has no beginning; therefore, it can have no end point - only as it is drawn.
