rhombus. The rhombus is a quadrilateral with all sides equal in length. It is also a parallelogram, so opposite sides are parallel and equal in length, and opposite angles are equal.
Yes, the opposite angles in a regular quadrilateral are equal.

A quadrilateral with four equal sides and two sets of opposite angles that are the same size is known as a rhombus. In a rhombus, all sides are of equal length, and the opposite angles are equal, while the adjacent angles are supplementary. Additionally, the diagonals of a rhombus bisect each other at right angles and are not necessarily equal in length.

There are many types of polygons to memorize. A parallelogram is a quadrilateral, where the opposite or facing sides are equal in length and the opposite angles are equal.
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 rhombus is a 4 equal sided quadrilateral with equal opposite acute angles and equal opposite obtuse angles with diagonals that bisect each other at right angles.

A quadrilateral with four sides of equal length is called a rhombus. In addition to having equal side lengths, a rhombus also has opposite angles that are equal and adjacent angles that are supplementary. If all angles are right angles, it is specifically a square, which is a special type of rhombus.
