This mode constructs the center of a conic. In particular, you can use this mode to construct the center of a circle. For general conics the center is the intersection of its axes of symmetry. The center of a conic is sometimes useful for constructing a point on a movable conic.
Select a conic and construct its center.
This mode is not properly supported in non-Euclidean geometries. It always constructs the Euclidean center.
