Want this question answered?
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
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.
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°)

The given description fits that of a square which has 4 equal sides, opposite sides are parallel and it has 4 interior right angles
square
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
trapezoid is the answer!
rhombus
Rectangle
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.
A parallelogram, a rhombus, a square and a rectangle
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
