A baseball diamond has four bases (forming a square) that are 90 feet apart; the pitcher's mound is 60.5 feet from home plate. Approximate the distance from the pitcher's mound to each of the other three bases.
垒球场设四个垒，形成一个四方形，每垒之间相距为90英尺，投手的投球区土墩距离本垒板为60.5英尺。从投球区土墩到每其他三个垒近似距离是多少。
pitcher's mound to first base：第一垒的投球区土墩
pitcher's mound to second base：第二垒的投球区土墩
pitcher's mound to third base：第三垒的投球区土墩

棒球场地有四个垒组成一个钻石菱形，每边90英尺长，投球手墩距离击球手位置长60.5英尺。求投球手距离其他三个垒的长度。

即求投球手墩距离第一、二、三垒距离。

见图 钻石菱形的顶角是60度滴 所以 AB=BC=CD=DA=90 AE=60.5

所以DF=BF=45 CF=AF=45*根号3=77.94 EF=AF-AE=17.44

所以BE=DE=（EF^2+DF^2）^0.5=48.26

则距离一垒为48.26英尺，距离二垒77.94英尺 距离三垒48.26英尺
