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.
Rigid motion refers to a transformation of a geometric figure that preserves distances and angles, meaning the shape and size of the figure remain unchanged. Common types of rigid motions include translations (sliding), rotations (turning), and reflections (flipping). In essence, during a rigid motion, the pre-image and its image are congruent. This concept is fundamental in geometry, as it helps in understanding symmetries and maintaining the integrity of shapes during transformations.
A rigid transformation that does not result in a reversed orientation of the original image is a translation or a rotation. Both transformations preserve the orientation of the figure, meaning that the shape and arrangement of points remain unchanged. In contrast, a reflection is the rigid transformation that reverses the orientation.
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
Rigid is immovable, unbending. Semi-rigid can move in a limited way.

Transformations are called rigid because they do not change the size or shape of the object being transformed. In rigid transformations, distances between points remain the same before and after transformation, preserving the object's overall structure. This property is important in geometry and other fields where accurately transferring or repositioning objects is required.
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.

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.
I think "isometries" and "rigid transformation" are two different names for the same thing. Look for "isometry" on wikipedia.
Rigid transformations are those that do not change the shape or size of the object. They include translation (moving the object without rotating or resizing it), rotation (turning the object around a fixed point), and reflection (flipping the object over a line).
The identity transformation.
To show congruency between two shapes, you can use a sequence of rigid transformations such as translations, reflections, rotations, or combinations of these transformations. By mapping one shape onto the other through these transformations, you can demonstrate that the corresponding sides and angles of the two shapes are congruent.
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.
A rigid motion transformation is one that preserves distances and angles between points in a geometric shape. Anything that involves changing the size or shape of the object, such as scaling or shearing, would not describe a rigid motion transformation.
A rigid transformation that does not result in a reversed orientation of the original image is a translation or a rotation. Both transformations preserve the orientation of the figure, meaning that the shape and arrangement of points remain unchanged. In contrast, a reflection is the rigid transformation that reverses the orientation.
