Boy, I wish I remembered trigonometry...I hated that class. :)
Anyhow, I cut four half square triangles from square blocks measuring 4 7/8 by 4 7/8. And then I sewed them together to make a square. I was following a pattern in a book (Quiltmaker's Gift). I'd like to square up my squares, but it doesn't say what the finished size of the block is...
I've added a diagram here if it helps any. Each arrow is pointing to a side of the triangle which was 4 7/8 inches (before the were sewn together).
Can anyone tell me what the size of this block SHOULD be? It's somewhere between 6 and 6 1/2 inches.
