Given a right triangle with an acute angle $\theta$, the side of the triangle that is \emph{adjacent} to $\theta$ is the side of the triangle that is also a \PMlinkname{side}{Angle} of $\theta$ and is not the hypotenuse.
\begin{center}
\begin{pspicture}(0,-2)(4,4)
\pspolygon(0,0)(4,4)(4,0)
\rput[b](2,0){adjacent}
\psline(3.8,0)(3.8,0.2)
\psline(3.8,0.2)(4,0.2)
\psarc(0,0){0.3}{0}{45}
\rput[b](0.5,0.15){$\theta$}
\rput[l](0,0){.}
\rput[a](4,4){.}
\rput[b](4,0){.}
\end{pspicture}

When a phrase such as ``adjacent of an angle'' is used, one must determine from context whether it refers to this definition of adjacent or the other definition of \PMlinkname{adjacent}{Adjacent3}. Note that the definition supplied above is specifically for right triangles.
