Hais txog qhov no, pes tsawg degrees yog ib lub quadrilateral?

360 degrees

Tsis tas li ntawd, puas yog square 360 degrees? Txhawm rau nrhiav qhov ntsuas ntawm cov ces kaum sab hauv hauv a square , koj faib cov sum ntawm cov ces kaum ( 360 o) los ntawm tus naj npawb ntawm sab (4). Yog li ntawd, 360 o/4 = 90 o. Tag nrho cov anglesin a square sib 90o. Qhov sib npaug ntawm cov ces kaum ntawm a square yog 360 degrees.

Ua raws li qhov no, puas Quadrilaterals muaj qhov sib npaug?

Tsuas yog tsis tu ncua (tag nrho sab sib npaug thiab tag nrho cov ces kaum sib npaug ) quadrilateral yog square. Yog li tag nrho lwm yam quadrilaterals yog tsis xwm yeem.
