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 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"
Yes, because a square is a parallelogram
(1) Parallelogram A parallelogram is a quadrilateral with two sets of parallel sides. The opposite or facing sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are equal.(2) SquareA square is a regular quadrilateral. This means that is has four equal sides and four equal angles.(3) RhombusA rhombus is a quadrilateral whose four sides all have the same length. Opposite angles of a rhombus have equal measure. The two diagonals of a rhombus are perpendicular.(4) RectangleA rectangle normally refers to a quadrilateral with four right angles.ParallelogramSquareRhombus
