two! 2 are obtuse, 2 are acute If there are three right angles, then it makes it a parallelogram, ex: a square or a rectangle
None because it has 4 right angles
A parallelogram doesn't need any right angles in order to be a parallelogram.If it has any, then it's a special kind of parallelogram, called a "rectangle".Note:The way the properties of a parallelogram work out,if it has one right angle, then it has four of them.
A rhombus have 2 obtuse angles
There are 3 obtuse angles in a heptagon.

Two.
Except for the special case of a rectangle, a parallelogram must have two obtuse angles.
A pair of each. Unless it is a rectangle, in which case it has none.
It has two obtuse angles
There are no right angles in a parallelogram. A parallelogram only has right angles if it is a rectangle, in which case it has exactly four.
Parallelogram have 4 right angles. (because, square and rectangle is also parallelogram)

Usually zero. If your parallelogram happens to be a rectangle, 4.
