The word "opposite" is not particularly helpful.
The shape could be:
It could, of course, be a polygon with more than 4 sides.
It has 4 equal sides It has opposite parallel sides It has 2 opposite equal acute angles It has 2 opposite equal obtuse angle It has 2 diagonals that intersect each other at right angles
A parallelogram is such a shape.
The shape described is a parallelogram, specifically a rhombus. In a rhombus, opposite sides are equal in length, and opposite angles are equal. Additionally, none of its angles are 90 degrees, which differentiates it from rectangles and squares.
a square
The shape you are describing is a rectangle. In a rectangle, there are two pairs of parallel sides, and opposite sides are equal in length. Additionally, the opposite angles are equal, with each angle measuring 90 degrees. A square is a specific type of rectangle where all sides are equal in length.
A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length, and opposite angles that are equal. Two ways to describe a parallelogram could be as a shape with opposite sides that are both parallel and equal in length, or as a shape with opposite angles that are equal.

A shape with two pairs of opposite sides is a parallelogram. This includes rectangles, rhombuses, and squares, where opposite sides are both equal in length and parallel. Each pair of sides maintains the same distance apart throughout their length. Parallelograms also have opposite angles that are equal.
A shape with 2 sets of 2 equal sides is a parallelogram, which includes rectangles, rhombuses, and squares. In a parallelogram, opposite sides are equal in length, creating two pairs of equal sides. Additionally, all angles in a rectangle and all sides in a rhombus are either equal or congruent, respectively.
A square
A shape that has 2 pairs of equal sides and no right angles is a kite or a parallelogram. In a parallelogram, each side is equal to the one directly opposite; in a kite, the equal sides are adjacent to one another.
Any four-sided shape is a Quadrilateral.This includes squares, rectangles, and the ones with 4 non-equal sides.square: 4 equal sides, 4 equal angles, all 90 degrees, opposite sides parallelrectangle: 4 sides, 4 equal angels, all 90 degrees, opposite sides parallelrhombus: 4 equal sides, opposite angles equal (not all 4) ("diamond" shape)trapezoid: 2 opposite sides parallel, other two sides NOT parallel, angles generally not equal (looks like 2-D pyramid with top chopped off)irregular quadrilateral: the others that don't fit into these categories
