Lacking a context, I found the following references to four point H.\n\n* A type of barb in barbed wire.\n* A base for a hospital over-bed table.\n* A type of spreader beam for a crane.\n* A type of racing harness\n* The H in Scrabble is sometimes referred to as a 4 point H.\n* An advanced math concept (four-point H+\n3 correlator)

(m)\n\nBY  FOUR-CENTER  METHOD The   four-center   method   is   used   for   small ellipses.  Given  major  axis,  AB,  and  minor  axis, CD, mutually perpendicular at their midpoint, O, as shown in figure 4-45, draw AD, connecting the end points of the two axes. With the dividers set to  DO,  measure  DO  along  AO  and  reset  the dividers on the remaining distance to O. With the difference  of  semiaxes  thus  set  on  the  dividers, mark  off  DE  equal  to  AO  minus  DO.  Draw perpendicular  bisector  AE,  and  extend  it  to intersect the major axis at K and the minor axis extended  at  H.  With  the  dividers,  mark  off  OM equal  to  OK,  and  OL  equal  to  OH.  With  H  as a  center  and  radius  R1 equal  to  HD,  draw  the bottom  arc.  With  L  as  a  center  and  the  same radius as R1, draw the top arc. With M as a center and the radius R2 equal to MB draw the end arc. With K as a center and the same radius, R2, draw the  end  arc.  The  four  circular  arcs  thus  drawn meet,  in  common  points  of  tangency,  P,  at  the ends  of  their  radii  in  their  lines  of  centers

you need 2 moles of hydrogen for each mole of oxygen so for four oxygen moles you need eight hydrogens. oxygen is the limiting reactant and you can make four water moles

l = 40cm ,b= 40cm \nthen hypotenuse is  h*h =l*l + b*b \nh*h = 40*40 + 40*40\nh*h = 1600 +1600 \nh*h = 3200\nthen h = 56.5685 cm ans

no, actually it's 'four'

THE FOURTH DIMENSION AND ORTHOGONALITY\nA right angle is defined as one quarter of a revolution. Cartesian geometry arbitrarily chooses orthogonal directions through space which means they are at right angles to one another. Three orthogonal dimensions of space are known as, say the length, width and height . The fourth dimension is therefore the direction in space that is right angles to these three observable directions.\n\nFOUR-DIMENSIONAL GEOMETRY\nIn four spatial dimensions, Euclidean geometry provides for a greater variety of shapes to exist than in three dimensions. Just as three-dimensional polyhedrons are spatial enclosures made out of connected two-dimensional faces, the four-dimensional polychorons are enclosures of four-dimensional space made out of three-dimensional cells. Where in three dimensions, there are exactly five regular polyhedrons, or Platonic solids, that can exist, six regular polychorons exist in four dimensions. Five of the six can be interpreted as natural extensions of the Platonic solids, just as the cube, itself a Platonic solid, is a natural extension of the two-dimensional square.\n\nThe pentachoron is constructed out of 5 tetrahedrons for cells and 10 triangular faces, and is the four-dimensional analogue of the tetrahedron. The tesseract, or hypercube, is made out of 8 cubic cells and 24 squares, and is the four-dimensional measure polytope. The tesseract's dual, the 16-cell, is the equivalent of the octahedron, as they are both cross-polytopes.\n\nThe 120-cell and 600-cell are duals of each other, and are analogous to the dodecahedron and icosahedron, respectively. The 24-cell is the unique regular polychoron in that it has no three-dimensional equivalent.\n\nJust as the sphere, or 2-sphere, is a curved two-dimensional surface made up of all points equidistant from a given central point in three-dimensional space, the 3-sphere, a kind of hypersphere, is the space containing all points equidistant to a given central point in four-dimensional space. Every three-dimensional cross section of a 3-sphere is a 2-sphere.\n\nFORTH DIMENSION IN SPIRITUALISM\nFourth dimension or the world of four dimensions A new concept proposed by a turkish spiritualist. The term of “world of four dimensions” used by Bedri Ruhselman (1898-1960), founder of experimental neo-spiritualism, for to designate a world superior than the “world of spirits” called “spatium” by spiritualists. This term not contain a geometrical signification about fourth dimension like three dimensions of space (length (or depth), width, and height). This term means the world of evoluted spirits where there are not the colors and the forms. The world of four dimensions is inexplicable by our human concepts. Our concepts about the time and the space are not enough to conceive the time and the space of this superior world.The most subtle part of “spatium” is in contacte with this superior world. Bedri Ruhselman wrote 7 books. His latest book is not yet published.

A spatial point is an entity with a location in space but no extent (volume, area or length). In geometry, a point therefore captures the notion of location; no further information is captured. Points are used in the basic language of geometry, physics, vector graphics (both 2d and 3d), and many other fields. In mathematics generally, any form of space is considered as made up of points as basic elements.

tetrahedral\n\nmethane, CH4\nCH4 is composed of 5 atoms, 1 atom of carbon and 4 atoms of hydrogen covalently bonded.\nCarbon, C, is the central atom in the molecule.\nCarbon has 4 valence electrons (electrons that can be used in bonding).\nEach of carbon's 4 valence electrons will form a bonding pair with 1 of hydrogen's electrons.\nThe central carbon atom will therefore have no lone pairs of electrons and 4 bonding pairs of electrons,\nThe bonding pairs of electrons will repel each other as much as possible, so the molecule will be tetrahedral.\n\nCH4 is tetrahedral in shape
