# concentric

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

## Declaration

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

## Discussion

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.
