I found the word of the field trips at the Cooperhewitt, when I looked at the didactic panel of the Spun 2007-11, I saw this word of the title. ” Can a rotationally symmetrical form make a comfortable chair?” Since I learned the word “asymmetrical”, it was the other way of learning the opposite word.
