Center

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.

Synopsis¶

Select a conic and construct its center.

Caution¶

This mode is not properly supported in non-Euclidean geometries. It always constructs the Euclidean center.
