Solution

Only one circle can be drawn through any three non-collinear points. Here are the steps to understand why:

  1. Non-collinear points are points that do not lie on the same line. In other words, you cannot draw a straight line that passes through all three points.

  2. The definition of a circle is a set of points in a plane that are all an equal distance from a single point, known as the center of the circle.

  3. When you have three non-collinear points, you can always find a single point (the center) that is an equal distance from all three points. This is known as the circumcenter of the triangle formed by the three points.

  4. Once you have found the circumcenter, you can draw a circle with the circumcenter as the center and the distance to any of the three points as the radius. This circle will pass through all three points.

  5. No other circle can be drawn that passes through all three points, because any other circle would have a different center and/or radius, and therefore would not pass through all three points.

So, the answer is that only one circle can be drawn through any three non-collinear points.
