Yes providing that they are regular 5 sided pentagons otherwise no if they are irregular pentagons
Yes
Sometimes. For a regular pentagon, all the sides and interior angles are congruent. However, this isn't the case for some pentagons.
No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.
Some are some are not. Two regular pentagons with one equal side are congruent.
Pentagons can be classified based on their side lengths and angles. The main types include regular pentagons, which have all sides and angles equal, and irregular pentagons, which have sides and angles of varying lengths. They can also be categorized as convex pentagons, where all interior angles are less than 180 degrees, and concave pentagons, which have at least one interior angle greater than 180 degrees. Additionally, pentagons can be further classified into specific types like cyclic pentagons, which can be inscribed in a circle, and self-intersecting pentagons, also known as star pentagons.

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).
I assume you mean a regular dodecahedron. A regular dodecahedron has twelve faces, each of which are regular* pentagons. *(all sides are congruent, all angles are congruent)
Two pentagons that have corresponding angles congruent. First equals the first, second equals the second and so forth.
All right angles are congruent, and all straight angles are congruent.
No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.
Pentagons do not have to be regular. Elongating one side will skew two angles and make them non congruent with the other three, creating an irregular polygon.
Rectangles have all angles congruent,
Some are some are not. Two regular pentagons with one equal side are congruent.
No, pentagons to not have right angles.
a polygon that has all angles congruent is an equiangular .....
