Yes it does - it has two pairs of equal angles.
a parallelogram has 4 angles it is pretty much a rectangle that is tilted
Rhombus
rectangle
They are supplementary.
360
Four.
Yes, and adjacent angles are supplementary (add to 180°)
Not sure about a parallelgram, but a parallelogram has 4.
A parallelogram looks like a tilted rectangle with 2 equal acute opposite angles and 2 equal opposite obtuse angles whereas a rectangle has 4 equal angles of 90 degrees.
4 sides
No but they are both 4 sided quadrilaterals
It depends. Most parallelograms don't have all right angles. However, there is a special type of parallelogram that has all right angles. You probably know this shape by its proper name, a rectangle.
