Hint: A polygon with ten sides is called as a decagon. From there, a polygon with any number of sides till nineteen sides, a prefix name which implies the name relating to the number of the sides is added to the suffix decagon. From a ten sided polygon to the nineteen sided polygon, the name of the polygon ends with ‘decagon’.
Complete step by step solution:
Now let us learn more about polygons. Polygons are two-dimensional shapes. A polygon with equal sides is called a regular polygon, otherwise it is called an irregular polygon. The polygons are divided into two types depending upon the measure of the angle as concave and convex polygons. If any of the polygons has an interior angle greater than \[{{180}^{\circ }}\], then it is called a concave polygon.
Now let us find out the name of the \[18\] sided polygon.
The \[18\]sided polygon means nothing but a polygon with \[18\] sides. It is known as “octadecagon” or “octakaidecagon”. As we know that octa means nothing but eight and deca means ten. Together the name indicates eighteen. Also any polygon can be called with its number of sides and adding the suffix ‘gon’ to it. So the \[18\] sided polygon can also be called as \[18\]-gon.
The figure of the octadecagon looks as shown below.
This is a regular octadecagon since all of the sides are equal.
Note: The names of the polygons can be remembered in a simple way( not all of them but a few can be related and remembered). A quadrilateral can be remembered by relating to a quad-bike as it has four wheels. Octagon can be related to octopus as it has eight tentacles. Decagon can be related to our decimal system as it has ten digits and so on.
