1st paragraph all the way up to c2 : what is the squares in this sentence? I put question marks in my confusions. the two 'paragraphs' or 'whatever' I boxed are both messed up, like its both confusing when I read them one 'whatever' by one 'whatever'. In the 'four triangles can also be arranged in this large square to leave a central space..... what does >>>IN<<<<THIS LARGE SQUARE mean? (PICTURE ATTACHED TO THE PASSAGE) only this part (the "in the square") is confusing.

and the last one is hard to visualize and understand. If you could explain a simple process I will give you 5 stars. I promise. No lie
