Inkinga ye-parallelogram evumayo (inkinga ye-MIYA)
S.Miyazaki (Novemba 13, 2017)
Lena inguqulo ephakeme ye-"Inkinga kaLangley *" ku-geometry yangaphakathi ngo-1922.
I-parallelogram enezinxantathu ezine ngaphakathi ikhonjiswe ngama-angles X, Y no-Z, njengoba kubonisiwe kumfanekiso. I-parallelogram enezinxantathu ezine ngaphakathi ngaphakathi kangangokuthi wonke ama-angle akhiwe ngamaphethelo ne-diagonals anenani eliphakeme ngezinga, kubizwe lapha "i-parallelogram enezingalo eziningana".
Qinisekisa ukuthi kukhona "i-parallelogram eyodwa kuphela enezingalo eziningana", futhi unikeza amanani ama-integer angama-X, Y no-Z we-triangles ngaphakathi.
Lapha sikhiphe amacala akhethekile we-parallelogram njengama-rhombuses (Y = 90 °), izikwele kanye nama-rectangles (X + Z = 90 °), ngenxa yezixazululo ezincane.
Ngaphezu kwalokho, asikwazi ukuhlukanisa phakathi kwe-parallelogram kanye nesimo sayo esiyingqayizivele sesibuko / isakhiwo sayo sokulinganisa.
