# 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)`

<table><thead><tr><th width="231">Input</th><th>Description</th></tr></thead><tbody><tr><td>angle</td><td>the angle of rotation in radians/degrees depending on angle mode</td></tr></tbody></table>

What is actually happening in the above example is 👇

### 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**

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://learnpython.strivemath.com/p5-python-web/reference/built-in-functions/rotate.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
