The answer depends on what attributes you want to use for classification. These could be:number of sides (vertices),whether or not all sides are equal,whether or not all angles are equal,whether or not all sides and angles are equal (regular),number of parallel sides,number of perpendicular sides,order of rotational symmetry,number of lines of symmetry,convex or concave,various combinations of the above.
All polygons do not necessarily have a specific name. It is accepted practice to use the number of sides of the polygon as the name if one is not given or known. For example a 37-ogon
Triangles, squares and hexagons. That is if they all have to be the same. If you use different regular polygons, you can tile a flat surface with triangles and 12-sides or with squares and 8-sides for example.
use the inverse sine or cosine or tangent
A decagon has 10 sides and 10 angles.
The used it to study various aspects of triangular shapes: their areas, lengths of sides, angles. And since polygons can be divided up into triangles, some aspects of polygons can also be studied.
Whether or not an angle is even depends on the measurement unit that you use. Any angle that is is a whole number of degrees (other than 0), will be some irrational number of radians.Some irregular polygons with an even number of sides will have opposite sides that not parallel and angles that are not the same. However, not all irregular polygons will satisfy these requirements. There is no specific name for such shapes.

when you measure polygons that use right angles, like squares or rectangles.
They can use geometry by using angles and certain polygons/polyhedra.
They are regular polygons because you just multiply number of sides by the length of 1 side

Oh, dude, making generalizations about polygons is like trying to figure out why people still use fax machines. You just look at the sides and angles of different polygons, see what they have in common, and boom, you've got yourself a generalization. Testing it is like checking if your favorite food is still delicious - just try it out with different polygons and see if it holds up. Easy peasy, lemon squeezy!
you can describe it by its angles, or sides
Triangles, squares and hexagons. That is if they all have to be the same. If you use different regular polygons, you can tile a flat surface with triangles and 12-sides or with squares and 8-sides for example.
For polygons with large numbers of sides then just use the number as 250-gon, although it helps to state whether its a regular polygon or irregular.
