The general method is perhaps best illustrated by working through an \nexample.\n\nFind the shortest distance between the given lines, and the points of \nclosest approach on each line.\n\n  x     y-3     z                  x-5     y-8     z-2 \n --- =  ---  = ---   = s   and    ----- = ----- = ------ = t\n  1      1      -1                  3       7       -1\n\nThe common perpendicular is obtained from the vector product\n\n   | i   j    k |    = i(6) -j(2) + k(4)\n   | 1   1   -1 |\n   | 3   7   -1 |   \n\nSo common perpendicular is the vector (3, -1, 2) which can be written \nas a unit vector in the form  1/(sqrt(14)[3, -1, 2]\n\nThe vector connecting the given point on line (1) with the given point \non line (2) is  [(5-0), (8-3), (2-0)] = (5, 5, 2)\n\nThe scalar product of this with the common perpendicular in unit \nvector form is\n\n    5 x 3 + 5 x (-1) + 2 x 2        14 \n    -------------------------  =  -------   =  sqrt(14)\n            sqrt(14)              sqrt(14)\n\n\nSo the shortest distance is sqrt(14).\n\nNow to find the points of closest approach, we have:\n\nline (1) is  r = (0, 3, 0) + s(1, 1, -1)  =  [s, (3+s), -s]\nline (2) is  r = (5, 8, 2) + t(3, 7, -1)  =  [(5+3t), (8+7t), (2-t)]\n\nand we must find s and t. \n\nLine joining a general point on line(1) to a general point on line(2) \nis the vector\n\n  [(5+3t-s), (8+7t-3-s), (2-t+s)]\n\n  [(5+3t-s), (5+7t-s), (2-t+s)]\n\nand if s and t are points of closest approach this must be parallel to \nthe vector (3, -1, 2)\n\n     5+3t-s     5+7t-s     2-t+s\nso   ------  = -------- =  ------\n       3           -1        2\n\nFrom these equations s = -1  and  t = -1\n\nThe points of closest approach are therefore \n\non line(1)  (-1, 2, 1)      and on line(2)   (2, 1, 3)\n\nCheck that shortest distance is sqrt(14)\n\nshortest distance = sqrt((2+1)^2 + (1-2)^2 + (3-1)^2)\n\n                  = sqrt(9 + 1 + 4)  =  sqrt(14) \n\n\nIf you require the mid-point of these points, you get\n\n   -1+2  2+1   1+3\n   ----, ----, ----  =  [1/2, 3/2, 2]\n     2    2     2

a polygon with 5 sides is a pentagon.\n\nthis has two right angles so it would look like the picture of a basic drawing of a house.   see the pic of the house attached.\n\nhttp://www.thestationerystudio.com/index.cfm/fuseaction/catalog.viewProduct/productId/5214

If you're familiar with 2 D coordinates, 3 D coordinates should be no problem.  2 dimensions (with 2 (x,y) coordinates needed to describe a point) describe a flat surface (area) with length and width.  3 dimensions describe a space (volume) length, width and depth.  To describe a point 3 (x,y,z) values are needed.  4D adds time so that 4 values are needed to describe a point (in time).  Trigonometry and linear algebra become very important and helpful to solve problems.

Two dimensional. It's a cross-section of a cone (a conic section - look up Euclid).\n\nAn ellipsoid is a three dimensional solid that has three perpendicular cross-sections that are ellipses. Many other 3D shapes have elliptical cross-sections - a prolate or oblate spheroid is pretty much spherical except one cross section is elliptical (the earth is an oblate spheroid, a rugby ball or american football is prolate).

I'm afraid that with the given information, this would be impossible to determine. The only thing one could conclude from this information is that this polygon has an even number of sides. \n\nIt could be a square with sides of 3cm each\nIt could be a hexagon with sides of 2cm each\nIt could be an octagon with sides of 1.5cm each\nIt could be a decagon with sides of 1.2cm each\nIt could be a 12-gon with sides of 1cm each\n\nThe list is infinite unless you are given more specific information, such as the length of each side or the angles within the shape.

polygons are 2 dimensional shapes. they must have all straight sides and they must be closed. some examples are squares triangles, etc.  circles aren't because they  have 1 curved side.\n\npolyhedrons are 3-d shapes that have all flat sides and have no openings. ex: cube. spheres, cones, and cylinders are not because they all have curved sides.

a trapezoid ia a quadrilateral with only two parallell sides.\n\nas to figuring out what CD is, i'd need to know what MA and HT are (are they lengths of sides? measurements of angles?)  so, if you post those, then i'll see what i can do

polyhedron (pŏl'ēhē'drən) , closed solid bounded by plane faces; each face of a polyhedron is a polygon. A cube is a polyhedron bounded by six polygons (in this case squares) meeting at right angles. Although regular polygons are possible for any number of sides, there are only five possible regular polyhedrons, having congruent faces, each a regular polygon and meeting at equal angles. The five regular polyhedrons are also known as the Platonic solids, although they were known to the Greeks before the time of Plato. They are the tetrahedron, bounded by four equilateral triangles; the hexahedron, or cube, bounded by six squares; the octahedron, bounded by eight equilateral triangles; the dodecahedron, bounded by twelve regular pentagons; and the icosahedron, bounded by twenty equilateral triangles. The 18th-century Swiss mathematician Leonhard Euler showed that for any simple polyhedron, i.e., a polyhedron containing no holes, the sum of the number of vertices V and the number of faces F is equal to the number of edges E plus 2, or V+F=E+2

If by 3-D computing you mean something like the virtual Fileroom shown in the movie Disclosure, then no, there is no current viable OS like that.\n\nThe last "real" OS to claim "3D" was the NextStep OS developed by Steve Jobs that was purchased by Apple.  The etched buttons and designs were considered 3 Dimension by the standards of the time (Mac and Windows 3.1).  Those features have long been incorporated into virtually every OS, and are no longer "special"

Yes. A polygon is is a closed shape with multiple sides.  Check out all of the other types of polygons here: http://en.wikipedia.org/wiki/Polygon\n\nA rhombus is a polygon with equal sides and angles.  It looks like a slanted square. If you rotate it on end, it is a diamond shape.
