    en.wikipedia.org/wiki/Magic_circle_(mathematics)

    Magic circle (mathematics) Yang Hui's magic concentric circles – numbers on each circle and diameter (ignoring the middle 9) sum to 138. Magic circles were invented by the Song dynasty (960–1279) Chinese mathematician Yang Hui (c. 1238–1298). It is the arrangement of natural numbers on circles where the sum of the numbers on each circle ...

    en.wikipedia.org/wiki/Magic_triangle_(mathematics)

    A magic triangle or perimeter magic triangle[1] is an arrangement of the integers from 1 to n on the sides of a triangle with the same number of integers on each side, called the order of the triangle, so that the sum of integers on each side is a constant, the magic sum of the triangle. [1][2][3][4] Unlike magic squares, there are different ...

    en.wikipedia.org/wiki/Magic_square

    The primary square is obtained by rotating the root square counter-clockwise by 90 degrees, and replacing the numbers. The resulting square is an associative magic square, in which every pair of numbers symmetrically opposite to the center sum up to the same value, 26. For e.g., 16+10, 3+23, 6+20, etc.

  5. Missing square puzzle - Wikipedia

    The apparent triangles formed from the figures are 13 units wide and 5 units tall, so it appears that the area should be S = ⁠ 13×5 / 2 ⁠ = 32.5 units. However, the blue triangle has a ratio of 5:2 (=2.5), while the red triangle has the ratio 8:3 (≈2.667), so the apparent combined hypotenuse in each figure is actually bent. With the bent ...

    en.wikipedia.org/wiki/Pythagorean_theorem

    In mathematics, the Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.

  7. Miquel's theorem - Wikipedia

    en.wikipedia.org/wiki/Miquel's_theorem

    Miquel's theorem. Miquel's theorem is a result in geometry, named after Auguste Miquel, [1] concerning the intersection of three circles, each drawn through one vertex of a triangle and two points on its adjacent sides. It is one of several results concerning circles in Euclidean geometry due to Miquel, whose work was published in Liouville's ...

    Figure 3: Two given circles (black) and a circle tangent to both (pink). The center-to-center distances d 1 and d 2 equal r 1 + r s and r 2 + r s, respectively, so their difference is independent of r s. The solution of Adriaan van Roomen (1596) is based on the intersection of two hyperbolas. [13] [14] Let the given circles be denoted as C 1, C ...

  9. Geometric magic square - Wikipedia

    en.wikipedia.org/wiki/Geometric_magic_square

    Geometric magic square. A geometric magic square, often abbreviated to geomagic square, is a generalization of magic squares invented by Lee Sallows in 2001. [1] A traditional magic square is a square array of numbers (almost always positive integers) whose sum taken in any row, any column, or in either diagonal is the same target number.
