The equation for the size of an interior angle of an n-sided regular polygon is (n-2)180/n. When n=7, the interior angle of a regular sided shape would be 5x180/7 or approximately 128.57. The polygon in the question has an interior right angle (90 degree angle) and thus cannot be a regular shape. A 7 sided shape is called a heptagon. Thus, the shape described in the question is an irregular heptagon.
Providing that it is a regular 38 sided polygon then each interior angle will measure: 170o31'34.74''
equilateral triangle. im pretty sure
It is a regular polygon such as a square, an equilateral triangle or a regular 5 sided pentagon
A regular polygon has equal lengths of each side, AND the same angle between each of the sides. A Square is a polygon, an equilateral triangle is a polygon, a pentagon is a five - sided polygon, and so on.
A five-sided polygon is called a pentagon. A regular five-sided polygon is simply called a regular pentagon

A sixteen-sided regular polygon is called a hexadecagon or a hexakaidecagon.
Equilateral triangle.
A one thousand sided regular polygon is called a chiliagon.chiliagon (a polygon with 1000 sides)
An equilateral triangle.
A regular fifty-sided polygon is called a pentacontagon.
A 1000-sided regular polygon is called a chiliagon.
