对于“已知三角形的两边及其中一边对角,解斜三角形”的类型(也称为“SSA”型),文[1]、[2]、[3]、[4]、[5]分别作了介绍,并就其解的个数的判定给出了各具特色的解法,可前不久我校月考中的一题却出现了言之凿凿,而结果迥异的两派,于是笔者愿意在此作进一步探讨.例题△ABC中,a=27 For the type of “diagonal triangles on both sides of a known triangle and one side of it, the oblique skew triangle” (also called “SSA” type), [1], [2], [3], [4], [5] Introduced and given the unique solution to the determination of the number of solutions. However, the problem in the monthly examination of my school did not hesitate, but the two factions with different results, so the author is willing to In this case for further discussion. Example △ ABC, a = 27
