Similar objects.
"Same shape" is not exactly well-defined, but I think if they are "proportional" to each other (where taking one and multiplying *all* dimensions by a scalar yields the other), they are "isomorphic."
Such objects are said to be congruent.
"Identical" when talking to people, and "Congruent" in your math work.
Similar means that the figures are the same shape yet not the same size. If the figures are the exact same size and shape, then they are congruent.
Figures that have the same shape but not size are similar. Figures that have the same size are congruent.
Any two figures, polygonal or not, that are the same shape and size. Any two figures, polygonal or not, that are the same shape and size. Any two figures, polygonal or not, that are the same shape and size. Any two figures, polygonal or not, that are the same shape and size.
Similar objects.
Congruent
Such objects are said to be congruent.
Objects are congruent if they are the same size and shape, or an exact reflection of one another. If objects are not congruent, they are dissimilar in either size, shape or both.
Congruent objects are two or more objects that have the same shape and size, where one object can be mapped onto the other through rigid motions such as translations, rotations, and reflections. Essentially, congruent objects are identical in every way except for their position and orientation in space.
For two figures to be similar, they need to be the same shape, but not necessarily the same size.
Two objects having both the same size and shaped could be said to be 'congruent'.
Space is the separation of objects. Two objects cannot occupy the same place at the same time. It is also what gives objects size and shape. It is how we measure objects.

Two congruent objects will be of the same size and the same shape. One of them may be rotated or reflected with respect to the other.
No, not unless they are made of the same substance. Different substances have different densities, which means that the same volumes will have different masses.
