本文先给出三角形的外接圆半径、内切圆半径与面积之间的一个不等式 .定理 1 若三角形的外接圆半径为R ,内切圆半径为r,面积为S ,则Rr≥2 39S .证 设△ABC的三边长为a、b、c,由S =abc4R ,得  1ab 1bc 1ca=c4RS a4RS b4RS=a b c4RS =a b c4R·12 (a b c)r=12Rr,即  1ab 1bc 1ca=12Rr. ( 1)∵ S =12 absinC =12 bcsinA =12 casinB ,∴  1ab 1bc 1ca=sinC2S sinA2S sinB2S   =sinA sinB sinC2S .又易证 si…  相似文献
