a regular polygon
Not necessarily. A convex heptagon is a polygon but it need not have all sides and angles congruent.
That's a regular polygon.
Any regular polygon
It would be an irregular polygon that has not congruent sides and angles
Regular polygons have congruent sides and angles
A regular polygon is a polygon with congruent sides and interior angles.
A polygon that has congruent sides and congruent angles is called a Regular polygon. If the number of sides is given, you can be more specific. Some examples: 3 congruent sides/angles = equilateral triangle 4 congruent sides/angles = square 5 congruent sides/angles = regular pentagon 6 congruent sides/angles = regular hexagon ...and so on, by adding "regular" in front of the shape's name.

It is a regular polygon
Not necessarily. A convex heptagon is a polygon but it need not have all sides and angles congruent.
Their corresponding angles and corresponding sides are congruent.
A polygon with all sides congruent is a square.
It is an equilateral polygon. It is not a regular polygon. For the polygon to be regular, it is not enough for the sides to be congruent: all the angles need to be congruent as well.
