M'bukuli, tiwona momwe ngodya yolondola ilili, tchulani mawonekedwe akuluakulu a geometric momwe amachitikira, ndikuwunikanso chitsanzo cha vuto pamutuwu.
Tanthauzo la ngodya yolondola
Angle ndi mwachindunjingati ikufanana ndi madigiri 90.
M'zojambula, osati arc yozungulira yomwe imagwiritsidwa ntchito kusonyeza ngodya yotere, koma lalikulu.
Kokona yakumanja ndi theka la ngodya yowongoka (180°) ndipo mu ma radian ndi ofanana ndi Π / 2.
Maonekedwe okhala ndi ngodya zolondola
1. Square - rhombus, ngodya zonse zomwe zili zofanana ndi 90 °.
2. Rectangle - parallelogram, ngodya zonse zomwe zilinso zolondola.
3. Kokonati yakumanja ndi imodzi mwa ngodya zake zolondola.
4. Rectangular trapezoid - osachepera imodzi mwa ngodya ndi 90 °.
Chitsanzo cha vuto
Zimadziwika kuti mu makona atatu imodzi mwa ngodya ndi yolondola, ndipo ena awiri ndi ofanana. Tiyeni tipeze mfundo zosadziwika.
Anakonza
Monga tikudziwira, ndi 180 °.
Choncho, ngodya ziwiri zosadziwika zimakhala ndi 90 °
