請大大如果可以幫我翻譯ㄧ下>>The shape of a triangle is determined up to congruence by specifying two sides and the angle between them (SAS), two angles and the side between them (ASA) or two angles and an adjacent side (AAS).

Specifying two sides and an adjacent angle (SSA), however, usually yields two distinct possible triangles.謝!!
