Rectangular trapezoid chacho zvivako

Izvi geometric chimiro - rectangular trapezoid - harisi chete wemasvomhu asiwo mumuviri kuparadzira. Pashure pezvose, chii anopiwa muchikoro kwakarongwa, ndiyo yakabatana application. Somuenzaniso, anoziva kuti nzvimbo yacho rectangular trapezoid, unogona kuwana nyore miviri mumugwagwa imwe noruvara nokukurumidza inofamba. How kuzviita? Now funga.

Area dzakananga marudzi manhamba vari dzaona nenzira dzakasiyana. Nezvedu zvakafanira kuziva Verengai maviri nezvigadziko uye kukwirira. Wokupedzisira mumwe mativi akarara yakarurama akachinjikana. Total, hunokwanisa mugumisiro rinowanikwa sezvinotevera:

S = (a + b) * f / 2

Zvechokwadi, kuvimba uku hakusi kubviswa pasirin'i. Zvinoita kuti munhu anoziva pamusoro midline, rine zvose dzose uye rectangular trapezoid. Kana akasarudzwa netsamba m, ipapo kukosha zvinogona kuwanikwa se: m = (a + b) / 2. Mupfungwa Vaiisa chidimbu ichi pasi. You kuwana chinhu chakafanana Kureba bhokisi kuzivikanwa. Zviri pamusoro yokuderedza ichi chete dimikira wokutanga shoma kuyanzva kuvakwa. Kazhinji, nzira mativi rectangular trapezium kunoratidza nomukana yaitsiva H (kukwira) Pamativi urefu pa necheparutivi rworwendo 90. Vamwe chete vanofanira kunzwisisa kuti uyu unonzi wakarurama kuenzana pakati zvizhinji izvi.

Pakutanga, hatina kare ataurwa mukana kushandisa dimikira tsika mu wefizikisi. Zvikurukuru, vadzidzi vanofanira kuva rinozivikanwa Pfungwa noruvara nokukurumidza inofamba. Rectangular trapezoid ndozvazvakaita apo pakutanga velocity ndiyo razero, kubva kumhanyisa iri kugara. Kana basa yakatarwa kunodiwa kuverenga nzira zvaiyambuka mumamiriro ezvinhu akadaro, zvinokwanisika kuti kushandisa nzira yokuwana pachivara. Shanduka "munhu" achaita regai kureva rwendo rwose. Pakarepo zvinofanira kutaura kuti tiri kushanda Cartesian Coordinates. Zvadaro, "b" rinoreva nguva panguva yakanga kufadza nokukurumidza. Saka, kana ichingori saka kusvikira pakuguma noruvara nokukurumidza inofamba, ipapo b = 0. H nokuti kukosha tinogamuchira pamwero rakadzikama. Mushure dzinomiririra zvaunonyatsokoshesa. kugamuchira nzira, sezvo uchigona dzaona kubudikidza nzira S = V avhareji * t. Zvino imi munoziva sei unogona kubatsira rectangular trapezoid.

Kugadzirisa matambudziko vanofanira kuziva zvishoma inonyatsoita kuti kupiwa nhamba. Somuenzaniso, Verengai pamakona kurutivi vachida iri 180 inegumi. Diagonal panyaya imwe mativi ndiyo hypotenuse ane kodzero, triangle makumbo ari kuzivisa. Rangarira kuti kwete chero quadrangle, kunyanya mune rectangular trapezoid, denderedzwa zvinogona yakanyorwa. Kosi yechikoro anopiwa tsanangudzo dzakawanda, asi mumwe chinhu unofanira kubata. Somuenzaniso, chokwadi kuti rectangular trapezoid ane zvose zvatinosiita features, asi anewo mamwe zvinhu. Kufunga kuti mujinga ari mana, kuti lateral divi - matatu, uye diagonal unobatanidza pavo - 5. Pakazosvika Pythagorean theorem no, 3 * 3 + 4 * 4 = 5 * 5. Izvi zvinoratidza kuti ichi chinhu rectangular trapezoid.

Saka iwe vakasangana nomumwe geometric nhamba. Formula yokuwana munzvimbo yayo hachisi kudzidza, zvakakwana kunzwisisa musimboti kukarukureta.
