StametsI mean... I don't see the problem?
RandelungNo one said right angles.
Equal sides in a triangle are only possible if the corners are equal. So, 60⁰ each.
But its height cannot be half of base because of the same Pythagorean theorem
(1,5)²+(1,5/2)²=2,8125
sqrt(2,8125) ≈ 1,677, which is half of diagonal
So, we get 4 sides that are 1,5 in a parallelogram, but diagonals are 1,5 and 3,354, as opposed to both being 1,5 as shown on the picture
ObiIt’s funny how we say “because of such and such theorem” as if if some greek dude didn’t come up with his little story, the height could totally be half of base.
Decolonialize Maths!
We do need short names, but they don’t all have to be wyt guys. Pre-globalization, I’m sure many true maths statements were independently discovered by many people.
