Yes. If two figures are congruent, then you literally can't tell one from the other.
Anything that's true of one is also true of the other.
No, two rectangles do not have to be congruent if they have the same perimeter. Rectangles can have the same perimeter while differing in their length and width. For example, a rectangle with dimensions 4x6 has the same perimeter (20 units) as a rectangle with dimensions 5x5, but they are not congruent since their shapes and sizes differ.
Yes, congruent polygons have the same perimeter. Congruent shapes are identical in size and shape, meaning that all corresponding sides and angles are equal. Therefore, the sum of the lengths of their sides, which defines the perimeter, will also be equal.
No
Yes they are
They need not be congruent so the question is based on a fallacy.
I believe so, though I am not sure I can prove it.

Only if they have the same number of sides.
no because one rectangle may be 3x4 which the perimeter is 14 and one rectangle may be 5x2 which as well equals 14
if you mean congruent as allowing to rotate, reflect then yes 1 likely though
Yes, if the perimeters are the same, then both of them have side = perimeter / 4. And of course the angles are all 90°, since they are squares.
No, they might not have congruent angles, etc.
Congruent shapes are two shapes that are the same (angles, size perimeter/circumference)
