a rhombus
2 pairs of consecutive congruent sides
Trapezoid.
they have 4 sides of equal lenght and they have 2 pairs of parellel sides
yes it can it actually has 2 pairs of consecutife sides that are congruent
a rhombus
It is an isosceles trapezoid
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).
2 pairs of consecutive congruent sides
Trapezoid.
A rectangle has 4 congruent angles. 90 degrees. It is also a parallelogram, 2 pairs of congruent sides.
A square
It has 2 pairs of equal opposite parallel sides
This shape would be a square.
2 pairs, the sides opposite each other are congruent to each other
they have 4 sides of equal lenght and they have 2 pairs of parellel sides
Rectangle
