Angles and sides are congruent when they are identical. A shape with four identical sides and angles is a square.
This is a parallelogram. The first requirement is 2 pairs of congruent sides where the congruent sides are not adjacent. This is like a rectangle (excluding a square) that has two pairs of congruent sides where the congruent sides are not adjacent. But the angles are not all congruent (as set in the question) which pushes the shape into the "next less regular" shape, the parallelogram. The angles will not all be congruent, but it will have 2 pairs of congruent angles. There is no way to avoid the 2 pairs of congruent angles because of the requirement that the shape must have 2 pairs of congruent sides (the first requirement).
Square, rhombus possibly a parallelogram
none exist.
a regular polygon
That is a mathematical impossibility. At least 2 angles have to be congruent in order for the shape to have 4 sides.
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.
Convex polygons with congruent sides and congruent angles are called regular polygons.
rectangle
A polygon with 2n sides (n>1) can have opposite angles congruent.
Congruent Figures has equal sides, angles, shape and size.
