One of the first things you learn as a toddler is that you can't fit a square peg in a round hole, no matter how hard you try. But as you grow up, you learn about more bewildering and complex shapes that exist in two or three dimensions and often have a bizarre set of physical properties, from a center of gravity in an unexpected location, to the ability to spin in one direction and not the other, to being technically innocent but thoroughly reminiscent of something very naughty indeed.
Some shapes derive their names from Greek or Latin origins, while others are named for the popular toy, tool or symbol that makes use of them. Some appear in everyday life, whether by design (literally) or simply baked into nature's lines in the form of sunflowers and golden ratios. Others are rarer, meaning you might not recall their names - mainly because you don't necessarily need to remember the name of a twelve-sided shape in order to get through your ordinary day. Either way, there was probably a time that you knew all of their correct names, even if just to get yourself through the SAT. So click on through and let's see how much you've retained!
