Fahmidda Xarunta Cufis-jiidadka
Shay adag waxaa loo arkaa inuu ka kooban yahay walxo badan sababtaas awgeed xoog cufisjiidadka Ku shaqaynta mid kasta oo ka mid ah walxahan. Si kale haddii loo dhigo, walax kastaa waxay leedahay miisaan u gaar ah. Xarunta cufisjiidadka walaxdu waa bar ku taal ama ku wareegsan walaxda halkaas oo miisaanka dhammaan qaybaha walaxda uu ku urursan yahay.

Haddii shay uu isku mid yahay (cufnaanta walxaha qaar waa isku mid ama shaygu wuxuu ka kooban yahay walxo isku mid ah) qaabka shayguna waa isku mid (tusaale ahaan afargeesle, leydi, goobaabin) markaas xarunta cufisjiidadka shayga waxay la mid tahay xarunta cufisjiidadka shayga oo ku taal bartamaha shayga. Saddexagal, xarunta cufisjiidadka waxay ku taal 1/3 saac, halkaas oo h = dhererka saddexagal.

Xarunta Qaacidda Cufisjiidadka
Haddii qaabka shaygu uu yahay mid siman oo shayguna uu yahay mid isku mid ah, markaas xarunta cufisjiidadka ayaa la mid ah xarunta cufisjiidadka shayga, halkaas oo xarunta cufisjiidadka Xarunta cufku waxay ku taal bartamaha shayga. Taas bedelkeeda, haddii shaygu uu yahay mid isku mid ah laakiin aan isku mid ahayn, booska xarunta cuf-isjiidadka shayga waxaa lagu go'aamin karaa qaacidada soo socota:
Macluumaadka:
x = bartamaha shayga ku yaal dhidibka x, y = bartamaha shayga ku yaal dhidibka y, A = aagga shayga.

Tusaalaha dhibaatooyinka

1. Su'aal Imtixaanka Qaranka ee 2011/2012 C61 No.12

Fiiri sawirka diyaarad isku mid ah! Goobta bartamaha cufisjiidadka ee nidaamka shayga ee jihada dhidibka y laga bilaabo barta Q waa…

A. 1,00 cm
B. 1,75 cm
C. 2,00 cm
D. 3,00 cm
E. 3,25 cm

Dood

Shayga u qaybi laba qaybood, qaybta 1aad = leydi, qaybta 2aad = saddexagal.
A₁ = (12,5)(2) = 25
A₂ = ½ (12,5-2,5)(3) = ½ (10)(3) = (5)(3) = 15
y₁ = ½ (2) = 1
y₂ = 1/3 (3) + 2 = 1 + 2 = 3
Isku-duwayaasha bartamaha cufisjiidadka shayga ee ku yaal dhidibka y:

Barta Q = bar madow oo ku taal salka bartamaha shayga.
Jawaabta saxda ah waa B.

2. Su'aal Imtixaanka Qaranka ee 2011/2012 A81 No.12

Booska xarunta cufisjiidadka ee shaxan diyaaradeed sida ka muuqata sawirka dhinaca ka xiga dhidibka x waa...

A. 4,5 cm
B. 4 cm
C. 3,5 cm
D. 3 cm
E. 2 cm

Shayga u qaybi laba qaybood, qaybta 1aad = leydi, qaybta 2aad = saddexagal.
A₁ = (6-0)(3-0) = (6)(3) = 18
A₂ = ½ (6-3)(6-3) = ½ (3)(3) = 4,5
y₁ = ½ (3) = 1,5
y₂ = 1/3 (6-3) + 3 = 1/3 (3) + 3 = 1 + 3 = 4
Isku-duwayaasha bartamaha cufisjiidadka shayga ee ku yaal dhidibka y:

Jawaabta saxda ah waa E.

3. Su'aalaha Imtixaanka Qaranka ee 2018

Fiiro gaar ah u yeelo weedhahan soo socda:

(1) Ku celi habka lagu go'aaminayo xariiqda kartoonka laga soo laalaadayo meelo kala duwan, oo calaamadee isgoyska labada xariiq inay yihiin bartamaha cufisjiidadka kartoonka.

(2) Cidhifyada dunta ku xidh irbadda oo miisaan saar oo irbadda ku dheji kartoonka.

(3) Sadar ku sawir dhibcaha ku yaal kartoonka.

(4) Calaamadee dhibcaha ku teedsan dunta ku taal kartoonka.

(5) sudh kartoonka adigoo haysta salka irbadda

Si loo go'aamiyo goobta uu ku yaallo bartamaha cufisjiidadka ee kartoon aan caadi ahayn, taxanaha saxda ah ee tallaabooyinka waa...

Dood

Taxanaha saxda ah ee tallaabooyinka waa 2, 5, 4, 3, 1.
