Kite
parallelogram
The shape described is a kite, which is a quadrilateral with two pairs of equal adjacent sides and one reflex angle. A kite has an axis of symmetry along the line connecting the midpoints of the non-congruent sides. The reflex angle in a kite is typically greater than 180 degrees, creating a distinct shape that is not a regular quadrilateral.
An arrow head
The sum of an angle and its reflex equal 360 degrees.

This is an arrowhead quadrilateral.
An arrow head
you can prove any one of these statements to prove that quadrilateral is a rectangle: -- Opposite sides are parallel and any one angle is a right angle. -- Opposite sides are equal and any one angle is a right angle. -- All four angles are right angles. -- Adjacent angles are complementary, and one of them is a right angle. -- Opposite sides are either equal or parallel, and area is equal to the product of two adjacent sides. -- Diagonals are equal.
Rectangle, possibly a square if the adjacent sides are also equal.
it is a angle
A reflex angle
It is also called an arrowhead. It is a kite with one of the vertices between equal sides "pushed in" so that it becomes a reflex angle.
Rectangle
The sum of an angle and its reflex equal 360 degrees.
