# Polymorphism

Different objects responding to the same method call in their own way.

## What is **Polymorphism**?

**Polymorphism** ("many shapes") means different objects can respond to the same method call in their own way. Tell every shape to `Draw()` and circles draw circles while squares draw squares. The calling code doesn't need to know which is which.

```csharp
List<Shape> shapes = [new Circle(), new Square()];
foreach (var shape in shapes)
{
    shape.Draw(); // each shape draws itself
}
```
