**fillPolygon** is a function that is part of gc.

Fills the polygon defined by the lines connecting the (x,y) points.

The polygon is not automatically closed; the first x-y coordinate pair must be repeated at the end of the array of points to draw a closed polygon.

This has been introduced in TI-Nspire OS 3.0 (*Changes*).

## Syntax

gc:**fillPolygon**({x(1), y(2), ..., x(n), y(n)})

Parameter | Type | Description |
---|---|---|

| number | x-coordinate of the first point |

| number | y-coordinate of the first point |

| numbers | x and y coordinates... |

| number | x-coordinate of the nth point |

| number | y-coordinate of the nth point |

## Example

`gc:fillPolygon({0,0, 0,100, 100,100, 100,0, 0,0})`

This draws a filled-rectangle (square, actually) whose points are at the given coordinates.
