Yes
The word for the same in math is congruent. For example, if there are two squares, both the exact same size, length, width etc., then the two shapes are congruent.
I believe so, though I am not sure I can prove it.
No, because even through they have the same perimeter you must show how you can get 16 as the perimeter in two different ways.
Every parallelogram has. (That includes squares, rectangles, and rhombera.)
If two squares have the same side length for all sides, then they are congruent.
If they have the same area.
Then they both will have the same perimeter
No
Yes
No !
They need not be congruent so the question is based on a fallacy.
yes
Only if they have the same number of sides.
No, not if they are squares.

the perimeter of a rectangle with two 5cm squares will be 30cm
