What is a hexagon? Having a slight parenting anxiety attack and I hate teaching my son something incorrect.
Wiktionary tells me that a Hexagon is a polygon with $6$ sides and $6$ angles.
Why the $6$ angle requirement?  This has me confused.
Would the shape below be also considered a hexagon?


Yes, It is Considered as a Hexagon. There is a difference between an Irregular Hexagon and a Regular Hexagon. A regular hexagon has sides that are segments of straight lines that are all equal in length. The interior angles are all equal with 120 degrees. An irregular hexagon has sides that may be of different lengths. It also follows that the interior angles are not all equal. Some interior angles may be greater than 180 degrees, but the sum of all interior angles is 720 degrees. Hope this gives u an idea about it.
