Let $\theta$ be an angle of a triangle. A side of the triangle is \emph{adjacent} to $\theta$ if it is one of the \PMlinkname{sides}{Angle} of $\theta$.
\begin{center}
\begin{pspicture}(0,-1)(5,5)
\pspolygon(0,0)(5,0)(4,4)
\rput[b](2.5,0){adjacent}
\rput[r](1.8,2){adjacent}
\psarc(0,0){0.3}{0}{45}
\rput[b](0.5,0.15){$\theta$}
\rput[l](0,0){.}
\rput[r](5,0){.}
\rput[a](4,4){.}
\end{pspicture}
\end{center}
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}{Adjacent2}. Note that the latter is specifically for right triangles.
