No
Yes they are
They need not be congruent so the question is based on a fallacy.
Not normally but yes when they are congruent to each other.
No. The corresponding sides and angles of the two shapes MUST be the same.
I believe so, though I am not sure I can prove it.
No

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)
Not normally but yes when they are congruent to each other.
No. They can me different sizes. For a shape to be congruent, they need to me same size and same shape.
