The 1st dot will need 14 lines.
The 2nd will need 13 since we have already joined the 1st to the 2nd.
The 3rd will need 12.
The 4th will need 11.
etc etc
14 + 13 + 12 + 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 105 lines.
well its true that every chord contains two points of the circumference of a circle 'cos a chord is the straight line between two points on the circumference
The points are all the same distance from the center of the circle. The distance between the center and any point is the radius of the circle.

Every diameter of the circle.
That means that a given circle doesn't have two or three diameters. For a given circle, there is a unique measurement, called its "diameter". It is the distance from one end to the other, passing through the center. Since the circle is defined as all the points that are at the same distance from a point (the center), all radii are the same distance; and the diameter is simply twice the radius.

Yes, and the two points are located on the circumference of the circle
well its true that every chord contains two points of the circumference of a circle 'cos a chord is the straight line between two points on the circumference
That point is known as the "center of the circle". Every circle has one.
Every set of three points is Concyclic !

The points are all the same distance from the center of the circle. The distance between the center and any point is the radius of the circle.
Every meridian of longitude is a semi-circle that joins the north and south poles.
A circle has infinitely many points of symmetry. Every straight line that passes through the center of a circle is a line of symmetry.
Every so-called "great circle" is (more or less) the longest circumference of the Earth that includes any two points. The great circle includes the shortest distance between the two points for travel along the Earth's surface.
Because from every point on the rainbow, the angle between the direction to thesun and the direction to your eye has to be the same angle. The only collectionof points that can do that is all the points on a circle.
