Rigid Motion Transformation Definition Math
While the pre image and the image under a rigid transformation will be congruent they may not be facing in the same direction.
Rigid motion transformation definition math. Rigid motion definition any transformation as a translation or rotation of a set such that the distance between points is preserved. So for example let s say we take this circle a it s centered at point a. And we were to rotate it around point p. And both of those are rigid transformations which means that the length between corresponding points do not change.
A rigid transformation also called an isometry is a transformation of the plane that preserves length. A transformation is when you take a shape and you move it in some way. The shape doesn t shrink. Reflections translations rotations and combinations of these three transformations are rigid transformations.
This differs from non rigid motion like a dilation. Rigid motion is otherwise known as a rigid transformation and occurs when a point or object is moved but the size and shape remain the same.
