Natiijada casharka

Waxaan qirayaa in dhammaan murabba'aha (prisms) ay leeyihiin laba weji isku mid ah oo geeso badan leh oo isbarbar socda (saldhigyada), iyadoo wejiyada kale ay yihiin isbarbar yaal (parallelograms) oo isku xira geesaha u dhigma ee saldhigyada.

Hordhac

Salaan dhamaan. Casharkaan waxaan si qoto dheer u eegi doonaa sifooyinka qaababka saddex-geesoodka ah ee loo yaqaan 'prism' (prism), sida loo magacaabo iyo noocyada kala duwan ee laga yaabo inaadan hore u arag. Waxaad horey uga fahantay qaababka joomatari ee sallaxa ah sida saddexagalka iyo leydiga, iyo sidoo kale sida loo xisaabiyo bedka iyo mugga qaababka sallaxa ah.

Muuji qoraalka

Prisms are 3D shapes with a cross-section that is a uniform polygon. All prisms will have a pair of parallel faces that are congruent. This polygon cross section is often used to name the prism. The sides connecting the bases are parallelograms.

- wejiga sare
- wejiga hoose
- wejiga bidix
- wejiga midig
- Jawaabta saxda ah:wejiga dambe
3. Wajiga hore iyo kan midig ee cuboid-kan ayaa leh bed isku mid ah. Waa kuwee wajiyada cuboid-kan oo la mid ah wajiga hore?
- wajiga sare
- wajiga hoose
- Jawaabta saxda ah:wajiga bidix
- wajiga midig
- wajiga dambe

1. Waa kuwee ka mid ah qaababkan 3D ee ah prism-yada (prisms)?
- Jawaabta saxda ah:a
- b
- c
- d
2. Qaabkan 3D waa prism. Wejiga salka iyo qaybta isgoysku waxay ahaayeen kuwa loo adeegsaday in lagu garto in qaabkan uu yahay prism. Tee mid ka mid ah hadalladan ayaa run ah?
- Jawaabta saxda ah:Wejiga salka iyo qaybta isgoysku waa inay is barbar socdaan.
- Wejiga salka iyo qaybta isgoysku waa inay isku qumman yihiin.
- Wejiga salka iyo qaybta isgoysku waa inay isku ekaadaan (congruent).
- Wejiga salka iyo qaybta isgoysku waa inay isla masaafo u jiraan.
- Wejiga salka iyo qaybta isgoysku waa inay labaduba yihiin barbaroodle (parallelograms).
3. Magacyadan kee ayaa ku habboon birkaan (prism)?
- birka lixaad geesood ee isosceles
- Jawaabta saxda ah:birka lixaad geesood
- birka lixaad geesood ee caadiga ah
- birka lixaad geesood ee aan caadiga ahayn
- birka lixaad geesood ee toosan
4. Ereyadaan kee ayaa loo isticmaali karaa qayb ka mid ah magaca priism-kan?
- toos ah (right)
- Jawaabta saxda ah:qaldan (oblique)
- barbaroodle (parallelogram)
- trapezium
- isosceles
5. Alex wuxuu yidhi: "Prism-kani waa prism leydi ah (rectangular prism), sababtoo ah wejigani waa leydi". Kee ayaa ka mid ah hadalladan ku saxsan?
- Alex waa sax sababtoo ah isgoysyada (cross-sections) ee barbar socda wejigan dhamaantood waa leydi.
- Jawaabta saxda ah:Alex waa khalad sababtoo ah kani ma aha wejiga saldhigga isgoyska (cross-sectional base).
- Prism-kani waa prism saddexagal qumman (right angled triangular prism).
- Prism-kani waa hubaal prism qumman (right prism) sababtoo ah waxaa jira xagal qumman.
