# adjacent

Let $\theta$ be an angle of a triangle. A side of the triangle is adjacent to $\theta$ if it is one of the sides (http://planetmath.org/Angle) of $\theta$.

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 adjacent (http://planetmath.org/Adjacent2). Note that the latter is specifically for right triangles.
