No, I don't think so. It is a square block, and one side of the square is two smaller triangles and the other side of the square is a larger triangle. I don't think that is Flying Geese block.
Thanks,

I know what you're talking about. I would call it a "half quarter square triangle", but it must have a proper name.
If you put four of the blocks together with the lighter of the small triangles toward the outside, you get "Double Pinwheel" according to "Around the Block" by Judy Hopkins, or "Windmill" according to Better Homes and Gardens' "100 Quilt Blocks".
I need to do more research...

Here's a link to a diagram of the Double Pinwheel:

Yes, one fourth of that block is what I am talking about!!! Thank you!! Now, if I can only figure out how to make that a 12 in square block!!
