![]() Packed with engaging exercises like identifying and describing basic 2D shapes, followed by quadrilaterals and polygons, coloring 2D figures, matching. Some examples of polygons are triangles, rectangles, and squares, and there are shapes with many more sides, like the hexagon. *At some point in the future I would like to play around with Google’s search, and figure out (to the best of my ability) how it deals with and/or/not/parentheses, and write about it on this blog. We have penned this printable set of identifying and naming 2D shapes worksheets that is easy to use for the novice and not-so-shape-savvy kids of kindergarten, grade 1, grade 2 and grade 3. From what I can tell it was John Conway and Antreas Hatzipolakis who completed the namings up to the millions. Here is what I found.Īpparently there are two naming conventions (one with kai’s and one without). For example, a polygon with 47 sides would be called tetracontakaiheptagon or a tetracontaheptagon (of course, in practice mathematicians usually opt for the more compact and boring 47-gon). One thing I found interesting while searching for information about polygons was their naming conventions. From triangles to decagons, from the natural world to man-made objects, there are many objects around us that form a polygon shape. Here is a graph to illustrate the relative popularity of the n-gons. Rectangle/quadrilateral/tetragon/quadrangle (4 sides)-1,748,450 hits. ![]() ![]()
