All quadrilaterals have two [pairs] of opposite sides and in most cases they are not equal.
- Opposite angles are two angles that don't share a side. A quadrilateral has two pairs of them. - Adjacent angles are angles that share one side. A quadrilateral has four pairs of them.
It is not possible for a quadrilateral in Euclidean plane geometry to have no equal angles and still have its opposite sides parallel.It's possible for a quadrilateral to have no equal angles and two of its sides parallel (opposite ones, obviously; adjacent sides can't possibly be parallel). That would be a trapezoid.
The quadrilateral you are describing is a kite. A kite has two pairs of adjacent sides that are equal in length, where each pair is not opposite to each other. This property distinguishes kites from other quadrilaterals such as parallelograms and rectangles, which have opposite sides equal. Kites also typically have one pair of opposite angles that are equal.

A quadrilateral with two acute angles and all sides the same length is a rhombus. In a rhombus, opposite angles are equal, so if there are two acute angles, the other two angles must be obtuse, making a total of four angles. This property, along with having equal side lengths, characterizes the rhombus.

A quadrilateral that has two sets of equal sides but is not a parallelogram is a kite. In a kite, two pairs of adjacent sides are equal in length, but the opposite sides are not parallel. This distinct property differentiates it from parallelograms, where opposite sides are both equal and parallel. Kites also have unique angle properties, such as one pair of opposite angles being equal.
A parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.
Parallelogram, quadrilateral Parallelogram means "All opposite sides are equal" Quadrilateral means "Four-sided"
