The curling sheet, the rink, looks like shown on the image below.
The concentric rings on both ends of the rink are called the house.
The center of the house is marked by the intersection of the centerline and the teeline, and is called the button.
The hogline lies parallel to the teeline, in front of the house.
The so called "Free guard zone" is the area between the hogline and the teeline excluding the house.
