The question is not sufficiently well defined: the answer depends on same as WHAT! A polygon with the same sides and angle measurements as the corresponding sides and angles of another polygon is a congruent polygon. A polygon in which all the sides are the same length and all the angles are of equal measure is a regular polygon.
A polygon that all sides and angles are the same measurement is a regular polygon.
regular polygon-all the sides are the same length and the angles have the same measurement. polygon-a closed plane figure whose sides are segments that intersect at their endpoints.
If by "the same measurement" you mean length, then you are referring to an "equilateral polygon", a flat / 2-dimensional figure whose sides are all the same length.
A regular hexagon is a polygon with six sides where all six angles have the same measurement. (And all six sides have the same length.) If the angles of a hexagon do not all have the same measurement, or if the sides are not all of the same length, then the hexagon is irregular.
A polygon with all sides and angles the same is called a "regular polygon."

Because Every Point On The Polygon Has The Same Amount Of Sides
All sides and angles are equal in measurement
Twelve. The number of sides and vertices in a polygon are always the same.
