在直角三角形中,"adjacent side"(邻边)是指与特定锐角相邻且不构成直角的那条直角边。具体来说:
几何图示
例如在直角三角形ABC中,若讨论角A的邻边:
$$
begin{aligned}
&text{邻边} = AB text{或} AC text{(取决于哪个边与角A相连且非斜边)}
&text{斜边} = BC
&text{对边} = text{与角A相对的边}
end{aligned}
$$
三角函数中的应用
邻边是计算余弦(cos)和正切(tan)的关键要素:
需要特别注意:邻边的指向会随着所选锐角的不同而改变,同一个直角边对于不同角度可能既是邻边又是对边。在坐标系中,邻边常对应x轴方向的投影。
