## Conic by Five Points

This mode constructs the unique conic that passes through five points. It is one of the basic modes for constructing a general conic.

### Synopsis

Select five points to create a conic.

### Caution

If four of the five points are collinear, the conic is no longer unique and a null element is computed.
