# concentric

A rounded corner style where the corner’s radius shares a center
point with the container shape’s corner radius.

```
static var concentric: Edge.Corner.Style { get }
```

## Discussion

When a corner is concentric to its container, the system
calculates the corner radius to equal the container shape’s corner
radius minus the distance between corners. When the system
calculates a zero radius, the corner is square.
