a rectangle (that is NOT a square) has 4 right angles and consecutive sides of unequal lengths.
A regular polygon has equal angles AND sides.
All sides unequal in length? You're not going to get this in planar geometry. You might get it in spherical, but you cannot get a flat shape to have all the same angle, yet have all unequal sides. It's not going to happen. â–
Hexagons with unequal sides and angles cannot be classified as regular polygons. A regular polygon is defined as having all sides and angles equal, which is not the case for a hexagon with unequal sides and angles. Therefore, while hexagons can take many forms, only those with equal sides and angles meet the criteria for being regular polygons.
a scalene triangle
A shape with four unequal sides is called an irregular quadrilateral.
An irregular polygon.
A pentagon. If the sides and angles are equal it is a REGULAR pentagon.
A right trapezium or an irregular quadrilateral.
Rhombus
a rectangle (that is NOT a square) has 4 right angles and consecutive sides of unequal lengths.
A Circle
something with eight or more sides* * * * * An irregular polygon is one with either two (or more) sides that are unequal or two (or more) angles that are unequal. So an isosceles triangle, for example, is irregular.
A regular polygon has equal angles AND sides.
All its sides are unequal, all its angles are unequal.

All sides unequal in length? You're not going to get this in planar geometry. You might get it in spherical, but you cannot get a flat shape to have all the same angle, yet have all unequal sides. It's not going to happen. â–
