Any regular polygon with 5n sides, or any 5n pointed star (where n is an integer)
a circle
Yes. Rectangles have four right angles.
A shape with 4 right angles would be a square or rectangle. A trapezoid does not have any right angles..

No, if it has right angles it is a special case, such as rectangle, but in general it does not have to have any right angles
Any regular polygon with 5n sides, or any 5n pointed star (where n is an integer)
Any regular polygon with 5n sides, or any 5n pointed star (where n is an integer)
the answer is 5 each tip of the star is a acute angle and each angle on the inside of the star is an obtuse angle. there are 5 obtuse angles and no right angles.
a circle
No, a cylinder does not have any right angles because it has two circles and a tube comprising it so as they do not have any right angles, the cylinder will not either.

Yes a square always has 4 right angles but a rhombus never has any right angles.
A polygon with six or more sides, in which four of the angles are right angles and the other angles are not. These others are of any type - as required. It cannot be a pentagon because, if 4 angles are right angles, the fifth would be 180 degrees!
It can.Quadrilateral means "four sides", and squares and rectangles do have right angles. Rhombuses are quadrilaterals, but do not have right angles.
