Bowling lanes are generally paved with maple trees. The entire fairway consists of 39 boards. There are signs on the seven boards respectively.
The centerline of the fairway is the 20th board. The logo on this board is particularly noticeable. The bowling pin group has three hidden pins removed. From the front, the pins are also divided into seven places, which are the straight line extension of the seven pitching marks. Therefore, the bowling ball rolls in a straight line along the marks and can definitely hit the connected pins.
The arrangement of bowling bottles is very coordinated and coherent. A large equilateral triangle contains nine smaller equilateral triangles. It can cause many complex and interesting geometric continuous changes, which is an important theoretical basis for knocking down bowling bottles.
The crosshair arrow is 15 cm long and is the largest mark on the fairway. It is also the basis for aiming for bowling. Directly aiming at the bowling pin is not a good aiming method, because the curve ball and the curve ball are “slanted eye cannons”. Curve, direct aim can’t hit at all. This requires the use of the front sight to correct, and the deviation value is calculated in advance.
