All pentagons are 5 sided polygons
All pentagons are regular or irregular 5 sided polygons
Yes providing that they are regular 5 sided pentagons otherwise no if they are irregular pentagons
If they are congruent they must be similar.
All pentagons have five sides. When you see a five sided figure you will always know it's a pentagon.
No. But if you restrict yourself to regular pentagons, then all regular pentagons are similar.
No, similar pentagons (or any polygon for that matter) must have corresponding congruent angles and all sides must be proportional to its corresponding sides. For example, if a square with a triangle on it is a pentagon, then a regular pentagon would not be similar to it (because corresponding angles are not congruent).
Yes they are. All ten angles are 54 degrees.
-- All regular (equilateral) triangles are similar. -- All squares are similar. -- All pentagons are similar. -- All hexagons are similar. . . . etc. Any regular polygon is similar to all other regular polygons with the same number of sides.

Two pentagons that have corresponding angles congruent. First equals the first, second equals the second and so forth.
All pentagons have five sides. When you see a five sided figure you will always know it's a pentagon.
No, it is true of all pentagons.
Yes, because they will have 5 equal sides and 5 equal angles
