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

Explanation

To solve the question step by step, we will analyze different pairs of circles and determine how many points they have in common.

### Step 1: Draw two circles that do not touch each other.
- **Description**: Draw Circle A and Circle B such that they are separate and do not intersect.
- **Common Points**: Since the circles do not touch, they have **0 common points**.

### Step 2: Draw two circles that touch each other externally.
- **Description**: Draw Circle A and Circle B such that they touch at one point (let's call it point X).
