# Simple Polygon

This example creates a map with a simple polygon representing the Bermuda Triangle.

### TypeScript

```// This example creates a simple polygon representing the Bermuda Triangle.

function initMap(): void {
const map = new google.maps.Map(
document.getElementById("map") as HTMLElement,
{
zoom: 5,
center: { lat: 24.886, lng: -70.268 },
mapTypeId: "terrain",
}
);

// Define the LatLng coordinates for the polygon's path.
const triangleCoords = [
{ lat: 25.774, lng: -80.19 },
{ lat: 18.466, lng: -66.118 },
{ lat: 32.321, lng: -64.757 },
{ lat: 25.774, lng: -80.19 },
];

// Construct the polygon.
const bermudaTriangle = new google.maps.Polygon({
paths: triangleCoords,
strokeColor: "#FF0000",
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: "#FF0000",
fillOpacity: 0.35,
});
bermudaTriangle.setMap(map);
}index.ts```

### JavaScript

```// This example creates a simple polygon representing the Bermuda Triangle.
function initMap() {
const map = new google.maps.Map(document.getElementById("map"), {
zoom: 5,
center: { lat: 24.886, lng: -70.268 },
mapTypeId: "terrain",
});
// Define the LatLng coordinates for the polygon's path.
const triangleCoords = [
{ lat: 25.774, lng: -80.19 },
{ lat: 18.466, lng: -66.118 },
{ lat: 32.321, lng: -64.757 },
{ lat: 25.774, lng: -80.19 },
];
// Construct the polygon.
const bermudaTriangle = new google.maps.Polygon({
paths: triangleCoords,
strokeColor: "#FF0000",
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: "#FF0000",
fillOpacity: 0.35,
});
bermudaTriangle.setMap(map);
}
index.js```

### CSS

```/* Always set the map height explicitly to define the size of the div
* element that contains the map. */
#map {
height: 100%;
}

/* Optional: Makes the sample page fill the window. */
html,
body {
height: 100%;
margin: 0;
}
style.css```
