Amanani eTrapezoidal – 1
Amanani eTrapezoidal zizonke iinombolo ezimbini okanye ngaphezulu ezilandelelanayo. Zifanelwe ligama lazo kuba wena
ingenza itrapezoid enamachaphaza amaninzi kangako, njengoko kuboniswe kwimizekelo engezantsi. Qaphela ukuba ukuba nechaphaza eli-1 phezulu
Umqolo ulula ingcamango yokuba yitrapezoid kancinci, kodwa kuvumelekile kula manani.
INGXELO
Bonisa ukuba onke amanani angaqhelekanga yiNombolo yeTrapezoidal.
UMBONO
Ngaba ungafumana amanani alinganayo angamaNombolo eTrapezoidal? Ngaba ungafumana amanye angengawo?
amaNqaku
INGXELO
Lonke inani elingaqhelekanga lelohlobo lwe-2n + 1. Kuba u-2n + 1 = n + (n + 1), oko kubonisa ukuba lonke inani elingaqhelekanga, elikhulu kuno-1, liyinombolo yeTrapezoidal.
UMBONO
Phakathi kwamanani okuqala ambalwa alinganayo, sinala alandelayo:
- 2: Ayisiyo trapezoidal
- 4: Ayisiyo trapezoidal
- 6: 6 = 1 + 2 + 3
- 8: Ayisiyo trapezoidal
- 10. 10 = 1 + 2 + 3 + 4
- 12: 12 = 3 + 4 + 5
- 14: 14 = 2 + 3 + 4 + 5
- 16: Ayisiyo trapezoidal
Kubonakala ngathi amandla e-2 awakhe abe yi-trapezoidal. Ndiza kulandela oko kwi-Puzzle of the Week kamva.
