Topic: Trapezoid


  
  Trapezoid - Wikipedia, the free encyclopedia
In anatomy, the trapezoid bone is a certain bone in the hand.
In an isosceles trapezoid, the base angles are congruent, and so are the pair of non-parallel opposite sides.
The area of a trapezoid can be computed as the arithmetic mean of the lengths of the two parallel sides, multiplied by the distance along a perpendicular line between them.

 Isosceles trapezoid - Wikipedia, the free encyclopedia
An isosceles trapezoid (isosceles trapezium in British English) is a quadrilateral with a line of symmetry bisecting one pair of opposite sides.
A rectangle is a special case of the isosceles trapezoid, where it doesn't matter which pair of sides you use.
The area of an isosceles trapezoid (or any trapezoid) is equal to the average of the bases times the height.

 AllRefer.com - trapezoid (Mathematics) - Encyclopedia
The parallel sides of a trapezoid are called bases and the nonparallel sides legs; in an isosceles trapezoid the legs are of equal length.
The median of a trapezoid is the line segment connecting the midpoints of the legs; it is parallel to the bases and equal to half the sum of their lengths.
The altitude of a trapezoid is the perpendicular distance between the bases.

 Math Forum: Ask Dr. Math FAQ: Quadrilateral Formulas
If a = c, the trapezoid is actually a parallelogram, so b = d, and the height and area cannot be determined from a, b, c, and d alone.
trapezoid (noun); trapezoidal (adjective); trapezium, plural trapezia (noun): The Greek word trapeza "table" was composed of tetra "four" and the Indo-European root ped- "foot." A Greek table must have had four feet (= legs).
For other Americans, however, a trapezoid is a quadrilateral with one and only one pair of parallel sides, in which case a parallelogram is not a trapezoid.

 Evolution of the Order of the Trapezoid Insignia
In any case, neither the trapezoidal pendant nor its bat-cover were in evidence around the Central Grotto by V/1970, when I was ordained to the Priesthood and appointed to the Council of Nine.
The background of this medallion was fl, with the trapezoid, trident, and 666 in white.
In addition to the pentagram and central trapezoid motif, note that each side-panel has a total of nine horizontal lines, and that the terminus of the lines suggests the Laguz-rune, Key to the life-force/reincarnation -- a not-inappropriate symbol for the theme of The Devil's Rain.

 Trapezoidal Window: Exploratorium Exhibit. Sometimes things are not as they appear.
When you look at a rectangular window that is angled away from you, the farther edge of the window appears smaller, and so the whole window appears to be trapezoidal.
But the rotating window in front of you really is a trapezoid.
When the shorter edge of this trapezoidal window moves closer to you, your brain refuses to see it as being closer; it assumes that the window is not rotating in the opposite direction.

 "Nazi Trapezoid" debunked
As indicated in the Order of the Trapezoid's statement, that dynamism and life worship was founded in a historical philosophy of German Romanticism, which significantly predates Naziism.
Moving on to Tim's 11/11/90 "The Nazi Trapezoid" itself, Tim Maroney opens his discussion of the supposed Nazi sympathy within the Temple of Set with, "But unsettling questions remain concerning this organization.
That is just one of the areas which they explore, and my impression (from reading their newsletter and talking to their members, since I myself am not a member of that Order) is that Nazi occultism is a fairly minor aspect of the Order.
