square or rhombus
All regular polygons with an even number of angles. All the angles of polygons with an odd number of angles are also equal but there are no "opposite" angles.
A parallelogram is a four-sided figure with opposite sides of equal length and angles not equal to 90 degrees (otherwise it would be a rectangle). Diagonally opposite angles will be equal, and adjacent angles will add up to 180 degrees.
Not sure exactly what the question is? But this type of figure would be known as a parallelogram
yes opposite angles are equal
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
A general quadrilateral.

A rhombus is a 4 equal sided quadrilateral with opposite parallel sides and equal opposite acute angles and equal opposite obtuse angles that all add up to 360 degrees.

yes opposite angles are equal
If one set of opposite sides is equal and parallel then both are. The figure is a PARALLELOGRAM and the opposite angles of course must be equal.(see related links below)Parallelograms include rectangles (four right angles) and rhomboids (two opposite acute angles and two opposite obtuse angles).A square is a type of rectangle (all sides equal).A rhombus is a type of rhomboid (all sides equal).Although a square could be considered an equiangular rhombus, it is usually considered a separate type of shape.
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
It is a Rhombus.
