a polygon with 4 right angles and 4 sides of the same length
A convex polygon with congruent sides and congruent angles is a regular polygon.Some regular pilgrims have specific names: Equilateral triangle and square
any regular polygon
A polygon with 2n sides (n>1) can have opposite angles congruent.
Not all polygons are regular by definition. An irregular polygon may have non-congruent sides or non congruent angles or both. A regular polygon will always have both congruent sides and angles.
Any polygon with 2n sides (n integer) where opposite sides are parallel, will have its opposite angles congruent.
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.
A square
No, it is not true that in a polygon all sides and angles are congruent. A polygon with all sides congruent is called a regular polygon, but there are also irregular polygons where the sides and angles can vary. For example, a rectangle has congruent opposite sides but not all sides are equal, and its angles are congruent but not all angles need to be equal in other types of polygons. Thus, congruence in sides and angles only applies to regular polygons.

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.
