Olee otú ịchọta a geometric square shapes

E nwere enweghi ngwụcha nọmba nke ụgbọelu ọgụgụ nke dị iche iche shapes dị ka na ihe ọjọọ. The nkịtị onwunwe nke niile iberibe - ọ bụla n'ime ha nwere ebe. Square shapes - bụ size nke ụgbọelu ji site ndị a na ọnụ ọgụgụ, kwuru na ụfọdụ nkeji. Nke a bara uru na-mgbe kwupụtara a mma nọmba. The unit ịtụ bụ ebe nke square, onye n'akụkụ ogologo hà otu (e.g., otu mita ma ọ bụ otu sentimita). Ndika ebe nke ọ bụla udi nwere ike gbakọọ amụba ọnụ ọgụgụ nke unit n'ámá n'ime nke ọ na-ekewa ke ebe nke otu square.

Ọzọ nkọwa nke echiche dị ka ndị a:

1. Square mfe shapes - scalar mma ụkpụrụ na-eju afọ ọnọdụ:

- nwere hà iberibe - hà uru nke ebe;

- ma ọ bụrụ na ọnụ ọgụgụ a na-ekewa akụkụ (mfe ọgụgụ), ya ebe - nchikota nke n'ámá nke data iberibe;

- a square na-enwe a n'akụkụ nke unit, bụ a unit ebe.

2. Square mgbagwoju udi shapes (polygons) - mma ụkpụrụ ndị nwere Njirimara:

- nwere hà polygons - otu ụkpụrụ nke ebe;

- ma ọ bụrụ na ndị polygon bụ a ole na ole ndị ọzọ polygons na ebe hà nchikota nke ikpeazụ ohere. A na-achị na-esetịpụ ezi na-abụghị overlapping polygons.

Dị ka ihe na-anabata axiom nkwupụta nke na-akpụzi n'ógbè (polygons) - mma ụkpụrụ.

Ịchọpụta na ebe nke a gburugburu na nyere iche iche na quantities chọrọ site n'ógbè nke a mgbe nile polygon dere na a gburugburu nke okirikiri - n'agbanyeghị eziokwu ahụ bụ nọmba nke n'akụkụ nēche ebighebi.

Square iberibe oge ufodu udi (aka ike shapes) enweghị definition naanị kpebisiri ike site ụzọ ha si ngụkọta oge.

Ngụkọta oge nke ebe n'oge ochie bụ onye dị mkpa bara uru nsogbu na ịchọpụta na size ala. Iwu maka ịgbakọ ebe nke a ole na ole narị afọ BC, e chepụtara ná Greek ọkà mmụta sayensị na kọwara na "Ihe" nke Euclid ka theorems. Na-akpali mmasị, iwu maka ịchọpụta ebe nke dị mfe shapes na ha - otu dị ugbu a. N'ámá geometric shapes enwe a curved ngwe, gbakọọ iji ịgba.

Na ngụkọta oge nke ebe nke dị mfe shapes (triangle, rektangulu, square), maara ihe niile akwụkwọ, dị nnọọ ezu. Optionally nwere ọbụna n'isi akwụkwọ ozi e usoro ọgụgụ ebe. Ịpụta ihe ọ na-echeta a ole na ole dị mfe iwu:

1. Iji gbakọọ ebe nke square, ọ dị mkpa iji mụbaa ogologo n'akụkụ onwe ya (ma ọ bụ na-ewu nke abụọ ogo).

2. The ebe a rektangulu na gbakọọ site amụba ogologo site obosara. Ọ dị mkpa na ogologo na obosara, e gosipụtara na otu nkeji.

3. The ebe a mgbagwoju na ọnụ ọgụgụ a gbakọọ site n'ike ya n'ime ọtụtụ mfe ma tinye n'ihi ebe.

4. The size of a rektangulu abahade ya abụọ triangles onye ebe hà na-hà ọkara nke ya ebe.

5. The ebe nke a triangle na gbakọọ ka ọkara ngwaahịa nke ya elu na a isi.

6. The ebe nke a gburugburu bụ hà bụ ndị square nke okirikiri na niile ụfọdụ ọnụ ọgụgụ nke «π».

7. gbakọọ ebe nke parallelogram dị ka ngwaahịa nke n'akụkụ n'akụkụ na-enweghị nke na n'akuku dina n'etiti ha.

8. Area nke a rhombus - ½ n'ihi amụba na-enweghị nke diagonals nke esịtidem n'akuku.

9. The nke ebe trapezoid chọta amụba ya elu na centerline ogologo nke bụ hà som pụtara nke bases. Ọzọ n'onwe nke definition nke ebe trapezoid - mụbaa matriks diagonal na imi n'akuku dina n'etiti ha.

Ụdị akwụkwọ ahụ na-karịrị na tụrụ atụ udi a na-ewere ọnụ ọgụgụ nke ngụkọta sel (nkeji nke ebe), ịtụkwasị ya na loop, mgbe ahụ, ọnụ ọgụgụ nke ndị na-ezughị ezu, nke a na-ekewa na ọkara.
