# rotate()

### Example

<div align="left"><figure><img src="/files/OfPk6mBvAbhO3iWwOgul" alt=""><figcaption></figcaption></figure></div>

```python
translate(width/2, height/2)
rotate(frameCount * 0.5)
trect(50, 50, 100, 100)
```

### Syntax

`rotate(angle)`

### Description

The `rotate()` function is used to **rotate the coordinate system** by a specified angle **about the current origin**. This means that any subsequent drawing or transformation function will be affected by this rotation.

**Positive** angles will rotate the plane from **+x to +y**, so:

* In `BOTTOM_RIGHT` coordinate system, positive angles rotate counter-clockwise.
* In `BOTTOM_LEFT` coordinate system, positive angles rotate clockwise.

**Negative** angles rotate the plane from **+x to -y**
