There is no specific name for them.
Rhombus: A Rhombus has four congruent sides but no right angles.
A quadrilateral has 2 pair of congruent angles and 4 congruent sides. What is the name of the quadrilateral
A rhombus is a type of parallelogram. Parallelograms are types of quadrilaterals. Everything that applies to quadrilaterals and parallelograms apply to rhombuses.Quadrilaterals have four sides and four angles.Parallelograms have at two pairs of opposite sides and opposite angles congruent. (Note: congruent is pretty much "equal", except for geometric figures). Both pairs of opposite sides are also parallel, hence the name "parallelogram".Rhombuses have all sides congruent.
A polygon that has congruent sides and congruent angles is called a Regular polygon. If the number of sides is given, you can be more specific. Some examples: 3 congruent sides/angles = equilateral triangle 4 congruent sides/angles = square 5 congruent sides/angles = regular pentagon 6 congruent sides/angles = regular hexagon ...and so on, by adding "regular" in front of the shape's name.
A quadrilateral with no right-angles would be a rhombus (or parallelogram) A rhombus has four sides, with opposite corner angles equal.
I can't find a name for it but an example would be a trapezoid. Some might have congruent angles but not all do.
A rhombus
That would be called a regular polygon, one with congruent(equal) side legnths and congruent angles.
A square
