I believe that the number of sides can be infinitely large. Just keep adding sides. The interior angles get arbitrarily closer to 180 degrees without actually reaching it. The exterior angles get arbitrarily closer to zero degrees without actually reaching it. This is even independent on the length of the sides.
There is no mathematical limit to the number of sides that a polygon can have. As the number of sides increases the polygon will become more and more like a closed curve - a regular polygon will become like a circle. The size of the polygon and accuracy of measurement will determine when it is no longer possible to distinguish between the polygon and the curve. Nevertheless, the two shapes will be mathematically different objects.
p = a. In a regular polygon with an even number of sides, every side is parallel to the one opposite it. So all a sides are parallel.
It is not possible to determine the length of the sides of a regular polygon simply from the number of sides.
You can use the formula D=S-2 where D is the number of possible diagonals and S is the number of sides the polygon has.
With a regular polygon: 360/exterior angle = number of sides
The polygon with the largest interior angle is a regular polygon, specifically a regular polygon with the greatest number of sides. In a regular polygon, all interior angles are equal, and the formula for calculating the interior angle of a regular polygon is (n-2) * 180 / n, where n is the number of sides. As the number of sides increases, the interior angle also increases. Therefore, a regular polygon with a very large number of sides will have the largest interior angle.

The number of sides possible in a polygon is a minimum of 3, with an unlimited maximum. For a regular polygon, as the number of sides approaches infinity, it approaches the shape of a circle.
It is not possible to name each polygon since there are infinitely many of them. There is no relationship between whether a polygon is regular and the number of sides or angles that it has. So, there is no way to determine, from its name, if a polygon is regular.
There is no largest polygon - just as there is no largest number.
The polygon may have 2n sides, where n is any whole number greater than 1

Number of lines of symmetry = Number of sides of the regular polygon
Effectively, the answer is that a regular polygon could have an infinite number of sides. However, when the number of sides reaches a thousand or so there is very little difference to the naked eye between such a polygon and a circle. For information : Some of the early calculations for pi were based on the very small difference between a polygon with a very large number of sides and a circle.
You can use the formula D=S-2 where D is the number of possible diagonals and S is the number of sides the polygon has.
