Peripendicular?

Question

please, can somebody tell me, what the exact meaning of "peripendicular" is and where is comes from ?
I actualy know the translation of the words: peri= (greek) around etc. and pendicular means somthing kind a "pendulum like". But it make no real sense.
In german we have a totaly other word for the meaning of "in 90° to something" written "senkrecht" (spoken thank-racht)
so maybe somebody can explaine me the origin of this word

Answer 1

From what you have written it seems to me that you know what the word means ("in 90° to something", "senkrecht") but are confused about the origin because you mistakenly think it's "per-i-pendicular" when it's actually "perpendicular" without the "i".
So yes, it is like a pendulum, not "around" but more like "to", or "with respect to", or something like that. Hold a pendulum (I mean anything that hangs down -from latin pendere- and hopefully stays still :) above a horizontal surface, and with respect to the surface the pendulum will be at that 90° angle you're looking for. Das Pendel hängt senkrecht ("pendicular") ZUR ("per") Fläche und bildet daher einen rechten Winkel zur bzw. eine Normale auf die Fläche. That's how I would imagine it, anyway...

Answer 2

per·pen·dic·u·lar ( P ) Pronunciation Key (pûrpn-dky-lr)
adj.
Mathematics. Intersecting at or forming right angles.

often Perpendicular Of or relating to a style of English Gothic architecture of the 14th and 15th centuries, characterized by emphasis of the vertical element.

Mathematics. A line or plane perpendicular to a given line or plane.
A perpendicular position.
A device, such as a plumb line, used in marking the vertical from a given point.

Answer 3

a straight line at right angles to another line
a Gothic style in 14th and 15th century England; characterized by vertical lines and a four-centered (Tudor) arch and fan vaulting
intersecting at or forming right angles; "the axes are perpendicular to each other"
plumb line: a cord from which a metal weight is suspended pointing directly to the earth's center of gravity; used to determine the vertical from a given point
vertical: at right angles to the plane of the horizon or a base line; "a vertical camera angle"; "the monument consists of two vertical pillars supporting a horizontal slab"; "measure the perpendicular height"
an extremely steep face

Definitions
--------------
1 a : standing at right angles to the plane of the horizon : exactly upright b : being at right angles to a given line or plane
2 : extremely steep : PRECIPITOUS
3 often capitalized : of or relating to a medieval English Gothic style of architecture in which vertical lines predominate
4 : relating to, uniting, or consisting of individuals of dissimilar type or on different levels

Origin of the Word
------------------------
Middle English perpendiculer, from Middle French, from Latin perpendicularis, from perpendiculum plumb line, from per- + pendere to hang

Answer 5

It just means not parallel. in other words think of two lines that will cross each other at a 90* angle it is just the english word for senkrecht. not sure of its origins but it has the same meaning. usually used in relation to geometry.

Es gerechte Mittel nicht parallel. denken Sie mit anderen Worten an zwei Linien, die an 90* sich kreuzen Winkel ist er das englische Wort für senkrecht. gerecht, das von seinen Ursprung nicht sicher ist, aber er hat die gleiche Bedeutung, die normalerweise in bezug auf eine Geometrie verwendet wird.

Answer 6

In geometry, two lines are considered perpendicular if one falls on the other in such a way as to create two equal angles.

From Latin: perpendicularis "vertical, as a plumb line"

couln't tell ya cuz I dont know
