No. A parallelogram has two parallel sides.
It could be a trapezoid having 2 right angles, an obtuse angle and an acute angle
if you think about what you just wrote you will find something interesting by defining a shape by this definition.
A rhomus has 2 parallel sides and all sides are the same length. It may or may not have perpendicular sides; if perpendicular it is a special case of a rhombus and is called a square
A rhombus.
parallelogram
Square
rhombus
Put 2 lines on the perpendicular sides and put 1 line for the parallel sides
A right angled triangle is an example of a shape with exactly 2 perpendicular sides.
For a shape to have parallel sides it needs at least 4 sides

A trapezoid is a shape that has 4 sides and 2 parallel sides. The sides that are parallel are called the bases.
Any regular polygon with 2k sides where k > 2. Also any such polygon that has been stretched in any directions parallel to its sides.
