Parallelogram construction with given elements
So i tried everything but i have no idea how to construct a parallelogram ABCD given this elements:

So i have a lenght of AB(base of parallelogram)
I have an angle where the 2 digaonals cut eachother.
And i have a hight from line AB

So pls tell me, because i cant figure it out (Crying)

Btw this forum seems really nice, i will sure try to come here more often now when i found about it (Clapping)

Hmm now i see this shoud probably go to University section, not to Pre-University, so it would be nice if mod can transfer it

Ok i hope this will clarify

So known elements are |AB|,h, and α.
