Yes
Proportional.
congruent
Two polygons are similar if:the ratio of the lengths of their corresponding sides is the same, andtheir corresponding angles are equal.
Yes, regular polygons will have all sides equal length, and all angles the same. If two polygons of the same number of sides are 'regular' then those two polygons will be similar (they may be scaled, for example).
No, you cannot.
All angle of two similar regular polygons must be equal.
similar polygons
yes.
Proportional.
Without specific details about the polygons in problems 1 and 2, I can only provide a general answer. If the polygons share the same number of sides, have equal corresponding angles, or are both regular polygons, they can be considered similar. Similar polygons maintain proportional relationships between their corresponding sides and angles. To give a more precise comparison, I would need the characteristics of the polygons in question.
congruent
Similar polygons are polygons for which all corresponding angles are congruent and all corresponding sides are proportional. From this definition we can say they have the same shape.
Two polygons are similar if and only if the corresponding angles are congruent
Two polygons are similar if:the ratio of the lengths of their corresponding sides is the same, andtheir corresponding angles are equal.
To be considered similar, two polygons must have corresponding angles that are equal, and their corresponding sides must be in proportion, rather than equal. This means that while the shapes of the polygons are the same, their sizes may differ. Thus, similar polygons maintain the same shape but can vary in scale.
polygons that have corresponding angles congruent and corresponding sides proportional
Corresponding angles are equal.The ratios of pairs of corresponding sides must all be equal.
