Lesson 637 Basic Shapes
Was reviewing Lesson 637, Basic Shapes, and all the comments that follow. Left feeling a little confused on how to say "a square" (noun) vs. "square shaped" (adjective) as well as "a rectangle" (noun) vs." rectangular" (adjective) and similarly, "a triangle" (noun) vs. "triangular" (adjective). here are my guesses.
