no they are not rigid.
The answer depends on the quadrilateral. Some have rotational symmetry or reflective symmetry and it is not possible to distinguish between these and translations.
Rigid is immovable, unbending. Semi-rigid can move in a limited way.
Yes, it is non-rigid.
a non rigid is a square and a hexagon
no they are not rigid.

Triangles are rigid, quadrilaterals are not - a square can be "squashed" into rhombus.
Proving that two figures are congruent using rigid motions involves demonstrating that one figure can be transformed into the other through a series of translations, rotations, and reflections without changing the size or shape of the original figure. This proof relies on the principle that rigid motions preserve distance and angle measures. By showing that the corresponding parts of the two figures align perfectly after applying these transformations, it can be concluded that the figures are congruent.
A translation is a type of rigid motion, which means it preserves distances and angles between points. In a translation, every point in a figure moves the same distance and direction. Rigid motions also include rotations and reflections.
Dilation, shear, and rotation are not rigid motion transformations. Dilation involves changing the size of an object, shear involves stretching or skewing it, and rotation involves rotating it around a fixed point. Unlike rigid motions, these transformations may alter the shape or orientation of an object.

Stable. Firm.
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.
