When calculating the arc of a circle, the most commonly used parameters are the radius and the chord. The problem is that these are not the only parameters that can be used. The angle, the distance between the points, and the middle point of the chord are also important.

In this app, you can use any two values for these parameters. The app will give you the remaining details of the circle, such as the angle and the middle point.

The app also supports several other parameters. These include the tangent, the middle point, and the length of the chord.

The app also supports the sector, the segment, and the area of the circle.
