no.
Sometimes. Remember, in order for two polygons to be similar, their angles must be congruent, and their corresponding sides must be proportional. In a rhombus, it is always possible for the angles to differ.
A polygon is a closed figure with 3 or more sides/angles, and the lines must always be straight. A circle isn't a polygon. Quadrilaterals are always polygons but polygons are not always quadrilaterals. So the answer is "sometimes."
Not all polygons are regular by definition. An irregular polygon may have non-congruent sides or non congruent angles or both. A regular polygon will always have both congruent sides and angles.
sometimes
Regular polygons.
no.
Circles and all regular polygons.
A regular polygon is always equiangular.

always
Equiangular (not eqiangular) polygons are equiangular. These can be, but need not be, regular polygons.
A square, pentagon, decagon, octagon are always regular polygons.
yae they always do:)
no. similar polygons do not have the same area. similar just means that they have the same angle measurements and are proportional.
Yes
similar polygons may not be congruent (different sizes) congruent polygons are always similar (equal in every geometric respect - including
