Yog li ntawd, koj yuav ua li cas thiaj nrhiav tau cov khoom ntawm lub quadrilateral?

Muaj ob cov khoom ntawm quadrilaterals : A quadrilateral yuav tsum kaw zoo li 4 sab. Tag nrho cov kaum sab hauv ntawm a quadrilateral sum txog 360 °

Parallelogram

  1. Cov kaum sab xis sib npaug.
  2. Cov sab nraud yog sib npaug thiab sib npaug.
  3. Diagonals sib sib zog nqus.
  4. Qhov sib npaug ntawm ob lub kaum sab xis yog 180 °

Kuj Paub, cov khoom ntawm cov duab plaub yog dab tsi? Isogonal daim duab Convex polygon

Ib tug kuj yuav nug, dab tsi yog cov yam ntxwv ntawm ib tug quadrilateral?

Quadrilaterals . Quadrilateral tsuas yog txhais tau tias "plaub sab" (quad txhais tau tias plaub, lateral txhais tau tias sab). A Quadrilateral muaj plaub-sab, nws yog 2-dimensional (ib lub tiaj tiaj), kaw (cov kab sib txuas), thiab muaj ob sab ncaj.

Dab tsi yog tus qauv ntawm quadrilateral?

P = a + b + c + d. A quadrilateral nrog plaub lub kaum sab xis thiab tag nrho plaub sab ntawm qhov sib npaug. (tag nrho plaub lub kaum sab xis yog li lub kaum sab xis). a = c, b = d.
