No. It could be a Rectangle or a square...
a kite (two pairs of adjacent congruent sides) or a trapezoid (one pair of parallel sides).
A kite is similar to a parallelogram in that both have opposite pairs of congruent sides. However, unlike a parallelogram, a kite does not have congruent opposite angles. Additionally, a kite has two pairs of adjacent sides that are congruent, while a parallelogram has all sides congruent.
Yes.A parallelogram with all congruent sides is called a rhombus. A square is technically a parallelogram with all congruent sides as well.
No. If you made a parallelogram with congruent sides it wouldn't necessarily have congruent angles. A square has to have congruent angles as well as congruent sides.

A parallelogram
Its opposite sides are congruent. Its adjacent sides may be but it's not necessary. If they are, then it's a special kind of parallelogram, called a 'rhombus'.
It must be a rhombus
No. It could be a Rectangle or 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).

In geometry, a kite, or deltoid is a quadrilateral with two disjoint pairs of congruent adjacent sides, in contrast to a parallelogram, where the congruent sides are opposite.
