How to set up a backgammon board
Understand the backgammon board.
It's important to understand the basics of the backgammon board before you begin to put your checkers on it. Here is what you need to know before you begin to set up your board :
The board has 24 narrow triangles called points.

Choose from:
(A). These triangles are used to make squares and circles, but they begin to require further study before placing your checkers on it. The sides must be labelled with v's on the front, and angled triangles are placed on the side where they dip into the box.;
(B). The triangles are between one's end and their corresponding corresponding points. Points are pronged, and are fixed when you place a ktouch string on the top of one's end.;
(C). These triangles are arranged in rows around the board, where they overlap by equal numbers. Each point points diagonally across the board.;
(D). The triangles alternate in color and are grouped into four quadrants of six triangles each. The board's four quadrants include player one's home board, player one's outer board, player two's home board, and player two's outer board.;
(D).
