    Hexagon - Wikipedia
    Regular hexagon A regular hexagon is defined as a hexagon that is both equilateral and equiangular. Its internal angle is one-third of a circle, equal to 120°. The Schläfli symbol denotes this polygon as . [2] However, the regular hexagon can also be considered as cutting off the vertices of an equilateral triangle, which can also be denoted as .

    Hexagon - Simple English Wikipedia, the free encyclopedia
    A hexagon is a polygon with 6 sides and 6 corners (vertices). Like regular triangles and squares, hexagons fit together without gaps. This is known as a tessellation. Because of this, they are often used for tiling floors. They are also quite common in nature. For example, the honeycombs in a beehive are hexagons.

    Important Geometry 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 $\sin^2\theta + \cos^2\theta = 1$.
