Khadadka dadab iyo xoolahoodii,

Perpendicularity waxaa loo yaqaan xiriirka u dhexeeya waxyaabaha kala duwan ee meel Euclidean - diyaarado si toos ah fallaadhaha subspaces iyo wixii la mid ah. In this article aan eegno dhow dadab iyo khadadka iyo sifooyinka sifo la xiriira ku daraa. Markaasuu laba xadhig laga yaabaa in dadab ku xusan (ama interperpendicular) haddii dhammaan afarta gees, kuwaas oo la aasaasay by ay isgoyska, foomka si adag a by sagaashan digrii.

Waxaa jira qaar ka mid ah guryaha khadadka dadab fulin diyaaradda:

• The yar xaglaha in loo sameeyay by isgoyska of laba xadhig isku diyaarad, loo yaqaan xagal u dhexeeya laba xadhig toosan. Halkaa marka ay marayso, ma tegi on dadab ah.
• Iyada oo hal dhibic oo aan ka tirsan line gaar ah, qaban karaan hal line oo kaliya, taas oo dadab iyo in line a siiyey.
• isla'egta of line a dadab iyo in ay diyaarada, oo macnaheedu yahay in line noqon doonaa dadab iyo in ay dhan khadadka in been ka on diyaarad this.
• Rays ama qaybaha been on the lines dadab iyo sidoo kale waxa loo gudbin doonaa sida dadab.
• Dadab iyo in ay wax kasta oo si toos ah u gaar ah waxaa loogu yeedhi doonaa qeybta line oo dadab tahay in oo uu leeyahay mid ka mid ah madax ka illaa iyo heer ay intersects the line iyo cut.
• Laga soo bilaabo dhibic kasta oo been ma on line ah la siiyo, waxaa suurtagal ah in ka tegid kaliya hal line toos ah, dadab iyo in ay.
• Dhererka line toosan dadab ka soo dhibic on line kale hoos loo gudbin doonaa meel fog ka si toos ah ay u barta.
• Xaaladda khadadka dadab waa in kuwa si toos ah loogu yeeri karaa, taas oo si adag u jareyso xagal quman.
• Distance ka barta gaar ah oo mid ka mid ah isku midka ah si toos ah u line labaad si toos ah loo gudbin doonaa masaafada u dhaxaysa laba xadhig isku midka ah.

Dhismaha khadadka dadab

Khadadka dadab dhisay on diyaarad iyadoo la kaashanayo geesoolayaasha ah. draftsman kasta waa in la dhasha maskaxda ku haysaa in feature muhiim ah oo geesoolayaasha kasta waa in ay had iyo jeer uu leeyahay xagal quman. In la abuuro laba xadhig dadab, waxaan u baahan nahay in la isu geeyo mid ka mid ah labada dhinac ee xagal midig ee our Barbaro geesoolayaasha ku haysta xadhig laga siiyo wax ka nafaqeeya toosan labaad oo ay la socdaan dhankiisa labaad oo xagasha midig. Oo sidaas ha loo abuuray doonaa laba xadhig dadab.

meel saddex dhinac-cabbir ah

Dhab ahaantii xiiso leh waa in khadadka dadab la fulin karo in meelaha saddex dhinac-cabbir ah. Xaaladdan oo kale, kuwaas oo loo gudbin doonaa laba xadhig si toos ah, haddii ay isku midka ah, siday u kala horreeyaan, mid ka mid ah laba xadhig kale ku jiifa isku diyaarad iyo sidoo kale dadab iyo in ay. Intaa waxaa dheer, haddii diyaarad dadab noqon kartaa khadadka laba kaliya in meel bannaan oo saddex geesood ah - saddex. Waxaa intaa dheer, in meelaha ku duugan tirada khadadka dadab (ama diyaarado) la sii kordhin karaa.
