Not necessarily. A convex heptagon is a polygon but it need not have all sides and angles congruent.
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.
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.
A polygon with all sides congruent is a square.
