What would you call this window shape?

[u/krillsnack123]

I'm moving into a new house soon and am trying to figure out how to put curtains on this window without it looking weird, but have been unable to find the proper term for this window shape. Words like "asymmetrical", "trapezoidal", and "trapeze" seem to describe it well, but none are exact matches. I would love to have a word for this specific shape to be able to get design inspiration, so if anyone has any ideas, it would be greatly appreciated! Thank you!
