Notes
KALUBALE
Yi aiki a kan tsarin ƙidaya ta amfani da waɗannan lambobi biyu. Na biyu yana buƙatar ƙirgawa sosai.
Babban alwatika a hagu:
Yana da ƙananan alwatika 9 (tushe na 1), alwatika 3 na tsaka-tsaki (tushe na 2), da kuma babban alwatika 1 (tushe na 3), jimillar alwatika 13.
Yana da ƙananan trapezoids guda 9 (tushe 2 saman 1), trapezoids guda 3 na tsakiya (tushe 3 saman 2), da kuma manyan trapezoids guda 3 (tushe 3 saman 1), jimillar trapezoids guda 15.
Yana da ƙananan parallelogram guda 9 (gefen 1 da 1) da kuma matsakaici parallelogram guda 6 (gefen 2 da 1), jimillar parallelogram guda 15.
Babban alwatika a dama:
Babban alwatika mai kusurwa uku a dama yana da ƙananan alwatika 16 (tushe na 1), ƙananan alwatika 7 na tsaka-tsaki (tushe na 2), manyan alwatika 3 na tsaka-tsaki (tushe na 3), da kuma babban alwatika 1 (tushe na 4), jimillar alwatika 27.
Yana da ƙananan trapezoids guda 18 (tushe 2 saman 1), ƙananan trapezoids guda 9 masu tsayi (tushe 3 saman 2), ƙananan trapezoids guda 3 masu tsayi (tushe 4 saman 3), manyan trapezoids guda 9 masu tsayi (tushe 3 saman 1), manyan trapezoids guda 3 masu tsayi (tushe 4 saman 2), da manyan trapezoids guda 3 (tushe 4 saman 1), jimilla 18 + 9 + 3 + 9 + 3 + 3 = trapezoids guda 45.
Yana da ƙananan parallelograms guda 18 (gefen 1 da 1), ƙananan parallelograms guda 18 (gefen 2 da 1), ƙananan parallelograms guda 6 masu tsayi (gefen 3 da 1), da kuma matsakaici parallelograms guda 3 (gefen 2 da 2), jimilla 18 + 18 + 6 + 3 = parallelograms guda 45.
