They can alter the location or orientation of the figures but do not affect their shape or size.
Rigid transformations, such as translations, reflections, and rotations, preserve the length, angle measures, and parallelism of geometric figures. By applying a combination of these transformations to two given figures, if the transformed figures coincide, then the original figures are congruent. This is because if two figures can be superimposed perfectly using rigid transformations, then their corresponding sides and angles have the same measures, establishing congruency.
triangle, because of the structural stability of the shape. it is the simplest geometric figure that will not change shape when the lenghth of the sides are fixed
Solids. Solids are the most rigid state of matter, so their particles are always fixed. Liquid particles have more freedom to move about, and gases have the most freedom.
Rigid is immovable, unbending. Semi-rigid can move in a limited way.
Arches and trianglesTriangles are used extensively because they are fundamentally rigid, because three line segments can define one and only one triangle. Compare a triangle to, say, a square, which could flex at its vertices to form a rhombus. If you take a square, however, and insert one diagonal, you basically have two triangles, which make the square rigid and not prone to collapse.Arches are also fundamental in architecture because of the way they distribute weight to the pillars that support them. Arches also convert horizontal and lateral forces to vertical ones.Read more: What_geometric_shapes_are_used_to_make_bridges_strong

I think "isometries" and "rigid transformation" are two different names for the same thing. Look for "isometry" on wikipedia.
The identity transformation.
Reflections, translations, and rotations are considered rigid motions because they preserve the size and shape of the original figure. These transformations do not distort the object in any way, maintaining the distances between points and angles within the figure. As a result, the object's properties such as perimeter, area, and angles remain unchanged after undergoing these transformations.
The chief feature of Archaic sculpture is the stylized representation of the human figure with an emphasis on geometric forms and rigid poses. These sculptures often exhibit a sense of idealized beauty and symmetry, portraying figures in a frontal stance with a fixed smile known as the "Archaic smile."
The only rectilinear figure is a triangle, or one composed of several triangles joined together.

Given two sets of angles and the included side congruent, we seek a sequence of rigid motions that will map Δ_____onto Δ___ proving the triangles congruent.
