![]() ![]() *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. 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. Learn Practice Download Polygons Polygons are defined as two-dimensional closed shapes that are formed by joining three or more line segments with each other. Here is a graph to illustrate the relative popularity of the n-gons. Rectangle/quadrilateral/tetragon/quadrangle (4 sides)-1,748,450 hits Solution: Hexagon Rectangle or quadrilateral Triangle Pentagon Example 2: Classify the given letters as open shape or closed shape.Triangle/trigon (3 sides)-2,633,500 Google hits.So here they are (drum roll, please), the top eight most popular polygons with 10 or fewer sides. Neither of these is a perfect solution, but hey, this is just a blog and not a submission to. * To solve the second problem I added the number of search results for each of the terms. To solve the first problem I entered the term geometry before the name of the polygon (for example I searched for geometry pentagon). Second, certain polygons have more than one name (rectangle, quadrilateral, tetragon, quadrangle). The first is that some of these words have nongeometric meanings like triangle and pentagon. The more hits, the more popular the term. A polygon is any flat shape or plane on a surface of a paper. These figures are collectively called polygons. So, I decided to google the terms and see which polygons received the most hits. Names of 3D geometric shapes: Figure: Definition: Cube: A cube is a three-dimensional shape which has 6 faces, 8 vertices and 12 edges. Both of my kids (one of whom is 2 years old) know what an octagon is, but I doubt my college students know the heptagon. (I feel bad for Heptagon, who apparently wasn’t invited to the party.) If any line drawn through the polygon can hit more than two other lines, then it's concave.I first posted this video back in September. It's convex if any line drawn through it intersects only two other lines. Included in this page are the following shapes: triangles. For example if a polygon has 41 sides, it would be called a 41-gon.Ī polygon is either convex or concave. Included with each shape is a small picture and a description of the properties the shape has and how it relates to other shapes. When the number of sides gets really high, mathematicians sometimes use the number of sides "n" and call it an n-gon. There are, of course, polygons with many more names and sides. Here is a list of polygon names depending on the number of sides they have, starting with three and ending with ten. ![]() Polygons are named for the number of sides they have. Some you've probably heard of before like squares, triangles, and rectangles. The following figures are enclosed and are polygons: The following figures are not enclosed and are not polygons: Enclosed - all the lines fit end-to-end and form a figure with no openings.Straight lines - these are called segments in geometry.Flat - this means it's a plane figure or two-dimensional.A polygon is a flat figure that is made up of straight lines and is enclosed.Ī few notes on the definition of a polygon that hopefully will help you remember: ![]()
