What kind of Polygon that has 14 sides?
forecastle/CC-BY 2.0. Assuming that it is a polygon, or a shape with closed sides, a 14-sided shape is called a tetradecagon or a tetrakaidecagon. Any polygon could also be called an n-gon, where n is the number of sides. Here, a 14-sided shape would be a 14-gon.
What do you call polygon with 14 sides?

What is polygon with 14 sides called?
– Three. Trigon or Triangle. – Four. Tetragon or Quadrilateral. – Five. Pentagon. – Six. Hexagon. – Seven. Heptagon. – Eight. Octagon. – Nine. Nonagon or Enneagon. – Ten. Decagon.
How many diagonals are in polygon with 14 sides?
From this number we have to subtract the 14 sides of the polygon, so: is the number of the diagonals. It is irrelevant if the polygon is convex or concave. From every vertex you can draw 14 – 3 = 11 diagonals. You can draw 14*11 = 154 diagonals, but you will have drawn each one twice.
