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.
The polygons are said to be similar.
Two polygons are similar if and only if the corresponding angles are congruent
yes
no.
sidelengths
The polygons are said to be similar.
no, they could be different size but same shape and be similar but not congruent.
Two polygons are similar if and only if the corresponding angles are congruent
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).
Prism
the two polygons are congruent if they are the same shape with the same measurements. If they can be flipped, rotated, and/or slid to look identical then they're congruent.
Any two polygons with a different number of sides are not similar.
yes
It is simply a shape which has two bases which are regular polygons. There is no special name for such shapes.
That the sides are of the same ratio and that the interior angles are the same.
Their sides are proportional and their interior angles are the same
If all angles of two polygons are the same the figures are similar (irrespective of rotation).
