Perimeters must be the same
For two 7 sided regular heptagons to be congruent they must be identical in shape and size.
They have all epual sides
Any Polygon can be a regular figure, if the figure has all straight sides and edges, with all the same length. If the decagon had all straight edges, sides, and same lengths of sides, it would be a regular figure. Otherwise, it would not, and would be an irregular Decagon. * * * * * That is not a correct answer. Any polygon, by definition MUST have all straight sides (which are the same as edges). What makes a polygon regular is that all the sides are the same length AND that all the interior angles are the same measure. Both these conditions must be met.
yes No it is not. All the angles of a regular shape must be the same and that is not the case with a rhombus.
it has seven sides and must look like a regular hexagon
For two 7 sided regular heptagons to be congruent they must be identical in shape and size.
They have all epual sides
The seven sides, in order, must be congruent, as must the seven angles.
They have sides of equal length.
No. Not all angles are equal, and not all sides are equal - and both conditions must be fulfilled for a "regular polygon".
All sides must be equal in length and each interior angle must be equal in degrees
Each interior angle of a regular heptagon measures 900/7 degrees.The interior angles of all polygons meeting at a point must sum to 360 degrees. But that would require 360 / (900/7) = 2.8 - that is you would require 2.8 regular heptagons to meet at each vertex. Since it is not possible to have a fraction of a heptagon. the tessellation required by the question is impossible.
Because it does't have 4 equal sides and 4 equal angles as for example such as a square.
Represenatives should make laws. Regular elections should be held. Individual rights should be protected.
All angle of two similar regular polygons must be equal.
No. For a polygon to be regular all its sides must be of the same length.
