I know the three points.

I know the radius of the circle

In summary, a major circular arc is a portion of a circle that spans more than 180 degrees, while a minor circular arc spans less than 180 degrees. To calculate the length of a major or minor circular arc, the formula L = rθ is used, where L is the arc length, r is the radius of the circle, and θ is the central angle in radians. The central angle can be found by dividing the arc length by the radius and converting the result. A major or minor circular arc can also be a complete circle if it spans 360 degrees. In this case, the arc length is equal to the circumference of the circle, 2πr.

There are three possible arcs, since anyone of the points can be defined to be the interior point.

A major circular arc is a portion of a circle that spans more than 180 degrees. It is also known as a "large" or "long" arc.

A minor circular arc is a portion of a circle that spans less than 180 degrees. It is also known as a "small" or "short" arc.

The formula for calculating the length of a major or minor circular arc is L = rθ, where L is the arc length, r is the radius of the circle, and θ is the central angle of the arc in radians.

The central angle of a major or minor circular arc can be found by dividing the arc length by the radius of the circle and converting the result to degrees or radians, depending on the unit of measurement used in the problem.

Yes, a major or minor circular arc can be a complete circle if the arc spans 360 degrees (or 2π radians). In this case, the arc length would be equal to the circumference of the circle, which is equal to 2πr.
