# adjacent

Given a right triangle^{} with an acute angle^{} $\theta $, the side of the triangle that is *adjacent ^{}* to $\theta $ is the side of the triangle that is also a side (http://planetmath.org/Angle) of $\theta $ and is not the hypotenuse

^{}.

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/Adjacent3). Note that the definition supplied above is specifically for right triangles.
