    Hypotenuse - Wikipedia
    A right-angled triangle and its hypotenuse In geometry, a hypotenuse is the side of a right triangle that is opposite to the right angle. [1] It is always the longest side of the triangle. The other two sides of a right triangle are called legs or catheti. [2][3]

    Hypotenuse Calculator
    With this hypotenuse calculator, you will quickly find the longest side of a right triangle. If you want to know the hypotenuse of a right triangle and how to find it, you'll discover the answers below, along with a simple example to clarify things.

    Hypotenuse of a Triangle – Definition, Formulas - Math Monks
    To find the hypotenuse of a right triangle when the length of a side and its opposite angle are known, we use the given formula, which is called the Law of sines.

    Right Triangle Calculator
    In a right triangle, the side that is opposite of the 90° angle is the longest side of the triangle, and is called the hypotenuse. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides.

    Aquí encontrarás qué es la hipotenusa de un triángulo rectángulo, cómo se calcula (fórmula) y ejercicios resueltos paso a paso.

    Hypotenuse - Math.net
    Since the hypotenuse of a right triangle is the longest side of the triangle, the 90° angle opposite it is also the largest angle of the right triangle. This also makes sense because the internal angles of a triangle sum to 180°.

    HYPOTENUSE Definition & Meaning - Merriam-Webster
    The meaning of HYPOTENUSE is the side of a right-angled triangle that is opposite the right angle.

    calcul hypotenuse et formule de Pythagore - Calculatrice.com
    L’orthographe française correcte est hypoténuse, avec un accent sur le é. Les recherches hypotenuse, hypothénuse ou hypothenus désignent généralement la même notion.

    Hypotenuse - Meaning, Theorem | Hypotenuse of a Triangle - Cuemath
    Hypotenuse Definition: In a right-angled triangle, the longest side or the side opposite to the right angle is termed hypotenuse. The hypotenuse is related to the base and the altitude of the triangle, by the formula: Hypotenuse 2 = Base 2 + Altitude 2.

    Important Trigonometry Terms
    • Sine (sin): The ratio of the length of the opposite side to the length of the hypotenuse in a right-angled triangle.
    • Cosine (cos): The ratio of the length of the adjacent side to the length of the hypotenuse in a right-angled triangle.
    • Tangent (tan): The ratio of the length of the opposite side to the length of the adjacent side in a right-angled triangle ($\tan \theta = \frac{\sin \theta}{\cos \theta}$).
    • Cosecant (csc): The reciprocal of the sine function ($\csc \theta = \frac{1}{\sin \theta}$), representing the ratio of the hypotenuse to the opposite side.
    • Secant (sec): The reciprocal of the cosine function ($\sec \theta = \frac{1}{\cos \theta}$), representing the ratio of the hypotenuse to the adjacent side.
    • Cotangent (cot): The reciprocal of the tangent function ($\cot \theta = \frac{1}{\tan \theta}$), representing the ratio of the adjacent side to the opposite side.
    • Hypotenuse: The longest side of a right-angled triangle, located opposite the right angle ($90^\circ$).
    • Radian: A unit of angle measurement based on arc length, where $2\pi \text{ radians} = 360^\circ$ ($1 \text{ radian} \approx 57.3^\circ$).
    • Unit Circle: A circle with a radius of $1$ centered at the origin $(0,0)$ in the Cartesian coordinate plane, used to extend trigonometric functions to any angle.
    • Pythagorean Identity: The fundamental trigonometric identity derived from the Pythagorean theorem, expressed as $\sin^2\theta + \cos^2\theta = 1$.
