{{ printedBook.courseTrack.name }} {{ printedBook.name }} The ratio between the lengths of the hypotenuse and the adjacent side in a right triangle for a specific angle, $\theta,$ is called the secant of $\theta$ and is written as $\sec(\theta).$

$\sec(\theta)=\dfrac{\text{hypotenuse}}{\text{adjacent}}$

The ratio is always the same for any given angle. If the hypotenuse is, for example, twice as long as the adjacent side, the ratio is $\sec(\theta)=\frac{2}{1}.$ This quotient holds true because the triangles are bound by similarity. Secant only states the **ratio** between the hypotenuse and the adjacent side, it gives no indication about the lengths of the individual sides.
