If it must use only line segments and must close in a space, the polygon with the fewest sides has to be the triangle (three sides and interior angles). (As it turned out, it didn’t get into the archive until 2013 due to a backlog; after that, students apparently found it and stopped asking us, suggesting that they hadn’t actually been assigned to write to us, which would have been thoughtless, but only to find an answer online.

For K-12 kids, teachers and parents. A rhombus is a type of parallelogram, and what distinguishes its shape is that all four of its sides are congruent.. (A Google image search for “diamond quilt pattern” provides some interesting contrasts.). A more flexible definition of shape takes into consideration the fact that realistic shapes are often deformable, e.g. Now, let me draw one of its diagonals. Any side of the rhombus potentially serves as its base. I would not expect the two words to be taught at the same level; and they are not in the same category so as to be compared: So, when a mathematician uses the word, if at all, it would probably be an informal term for “rhombus” (and since we already have that word, there is no need for another); but it is commonly used of a rhombus (not always, in my experience, a square, except in baseball) in a particular orientation (and therefore not really a mere shape). I do, however, find the Georgia standard that was referenced. In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length.
