a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
They may, or may not, be equal. If you are talking about a regular polygon, all angles are equal in measure. If it is not a regular polygon, the angles are most likely different.
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
An isosceles trapezoid has a pair of parallel sides and a pair of equal base angles
Opposite sides are parallel; opposite sides are equal; opposite angles are equal.
A parallelogram. (A rectangle if the angles are 90o)A parallelogram (which may also be a rectangle, if all four angles are equal to 90°)

trapezoid is the answer!
rhombus
Rectangle
No. A regular polygon has equal length sides and all the angles are equal. A rhombus has equal length sides, but only the opposite angles are equal. Since all the angles are not equal, the rhombus is not a regular polygon and is known as an irregular polygon.
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
