All sides equal but not all angles.
A rhombus is a quadrilateral with 4 equal sides and if the angles are also all equal that that rhombus is a square.
In general, a quadrilateral is not regular. Only the square has all its sides equal AND all its angles equal and so can be called regular.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
It's impossible for a quadrilateral to have no equal sides and have right angles.
It is a rhombus which has 2 equal acute angles and 2 equal obtuse angles

Diagonally opposite pairs of angles will always be equal, but the only time all angles in a quadrilateral parallelogram are equal is when that shape is a rectangle.
All sides equal but not all angles.
A square.
Yes, the opposite angles in a regular quadrilateral are equal.
A rhombus is a quadrilateral with 4 equal sides and if the angles are also all equal that that rhombus is a square.

Their sum does.
A rhombus
A regular quadrilateral is a square. It is a four-sided figure with all sides being the same length and all angles equal (right angles).
The sum of all inside angles of a quadrilateral equal 360 degrees.
