Draw different pairs of circles. How many points does each pair have in common? What is the maximum number of common points?

Solution:

In this, there are no common points.

In this, there is only one common point.

In this, there are two common points.

In a situation where two congruent circles are superimposed on each other, it can be understood as if we are drawing the same circle two times.

It is therefore concluded, there can be a maximum of two common points for different pairs of circles.
