Yes, polygons have the same number of sides and vertices.
None.But all polygons have the same number of sides as vertices.
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. triangle can have 3 sides all the same length and angle or it can have sides of differing lengths and angles. same for all other polygons.
similiar or proportional sides
The number of sides and vertices in any polygon is always the same.
yes
Polygons have the same number of sides and angles.
No, unless all its sides are equal in length, but that's the only time.
Regular polygons are when all the sides are same length and all the angles are the same size. Irregular polygons are shapes where the sides are not all the same and the angles are different.
All regular polygons with an even number of sides. Also rectangles.All regular polygons with an even number of sides. Also rectangles.All regular polygons with an even number of sides. Also rectangles.All regular polygons with an even number of sides. Also rectangles.
Yes providing that they both have the same number of sides.
