... are said to be congruent.
yes. polygons are closed shapes with no curves. i.e. circles are not polygons, squares are, triangles are, ect
No because polygons come in all different shapes and sizes but a quadrilateral is a 4 sided polygon.
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.
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.

Regular polygons.
Not all shapes are polygons. Polygons are shapes that have to have straight sides and be closed figures. So a shape that is curved would not be a polygon.
They are both the same shape but different sizes
Polygons are a special type of 2-dimensional shapes.
Polygons are shapes that have 3 or more sides
