As you see above, by definition, the hypotenuse is always the longest side in a right triangle and is always opposite the right angle. An adjacent side is any side that is, well, adjacent to a given …

Sin is the ratio of the opposite side to the hypotenuse, cos is the ratio of the adjacent side to the hypotenuse, and tan is the ratio of the opposite side to the adjacent side. They are often …

If they happen to be adjacent, then the two outside sides will form a right angle. When you have a right angle, the two sides of a right angle are considered to be perpendicular.

The pink and blue angles add up to 180 ∘ because they are adjacent and form a straight line.

"Supplementary," on the other hand, comes from the idea of supplementing or adding to form a straight line, meaning the angles add up to 180°. You can also remember that "C" comes …

Let's find out angle O: angle O is adjacent to line OE, opposite of line ZE, and our hypotenuse is OZ, so you can freely pick between any of the inverse trig functions to answer.

The hypotenuse of a right angle is simply that, the hypotenuse, regardless of any particular angles “perspective”. It is never (as I understand it) considered the “adjacent” or “opposite” side; it is …

Parallel & perpendicular lines Missing angles with a transversal Parallel lines & corresponding angles proof Missing angles (CA geometry) Proving angles are congruent Proofs with …

The secant (sec) The secant is the reciprocal of the cosine. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle.

So when we talk about adjacent angles, we're talking about an angle that has one of its rays in common. So for example, angle AGB has one of the rays in common, it has GB in common …
