If they have the same nuber of sides (angles) then always. If not then never.
So, overall, I suppose the answer is sometimes - depending on the number of sides.
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:)
similar polygons may not be congruent (different sizes) congruent polygons are always similar (equal in every geometric respect - including
Yes
All polygons can be irregular sense the requirements for a polygon to be irregular is for 1 or more sides to be unequal to the others. So a pentagon is sometimes a regular polygon. Hope that answers your question.
