2 dimensional (plane) figures can have three or more straight edges as sides. 3 dimensional (solid) figures can have four or more plane sides (faces). They can have fewer sides if the sides are not straight.
equilateral parallelogram
A Quadrilateral. Figures that have four equal sides are called squares. Whereas, other figures that have four unequal sides are called quadileterals
it is a plane and closed figure it has 4 corners and sides all the sides are equal
A polygon is any closed plane figure bounded by three or more straight sides.
square
A sguar.
A two-dimensional figure, also called a plane or planar figure, is a set of line segments or sides and curve segments or arcs, all lying in a single plane. The sides and arcs are called the edges of the figure. The edges are one-dimensional, but they lie in the plane, which is two-dimensional. The triangle, the pentagon, the hexagon and the circle are just a few plane figures. Prisms and pyramids, for instance, are three-dimension figures.
square or rhombus
A plane figure with eight sides is an octagon.

a plane figure having six sides is a hexagon
