  2. Degree (angle) - Wikipedia

    en.wikipedia.org/wiki/Degree_(angle)

    A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. [4] It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI brochure as an accepted unit. [5]

  3. Isometric projection - Wikipedia

    en.wikipedia.org/wiki/Isometric_projection

    Despite the name, isometric computer graphics are not necessarily truly isometric—i.e., the x, y, and z axes are not necessarily oriented 120° to each other. Instead, a variety of angles are used, with dimetric projection and a 2:1 pixel ratio being the most common.

  4. Eisenstein triple - Wikipedia

    en.wikipedia.org/wiki/Eisenstein_triple

    Similar to a Pythagorean triple, an Eisenstein triple (named after Gotthold Eisenstein) is a set of integers which are the lengths of the sides of a triangle where one of the angles is 60 or 120 degrees.

  5. Hexagon - Wikipedia

    en.wikipedia.org/wiki/Hexagon

    All internal angles are 120 degrees. A regular hexagon has six rotational symmetries (rotational symmetry of order six) and six reflection symmetries (six lines of symmetry), making up the dihedral group D 6. The longest diagonals of a regular hexagon, connecting diametrically opposite vertices, are twice the length of one side.

    N A Novile is an angle of 40°, which is 1 ⁄ 9 of the 360° ecliptic. An orb of ±1° is allowed. A Novile indicates an energy of perfection and/or idealization. [citation needed] Irreducible Multiples N 2 A Binovile is an angle of 80°, which is 2 ⁄ 9 of the 360° ecliptic. N 4 A Quadnovile is an angle of 160°, which is 4 ⁄ 9 of the 360 ...

  8. Vision span - Wikipedia

    en.wikipedia.org/wiki/Vision_span

    The visual field of the human eye spans approximately 120 degrees of arc. [1] However, most of that arc is peripheral vision. The human eye has much greater resolution in the macula, where there is a higher density of cone cells. The macula has a diameter of about 16 degrees of the retina. [2]
