Question

here are 4 triangles that have each been transformed by a different transformation. which transformation is not a rigid transformation?

Explanation:

A rigid transformation preserves distance and angle - measures. Translations, rotations, and reflections are rigid transformations. Dilation is a non - rigid transformation. In the given options, we need to identify the transformation that changes the size of the triangle. Option D shows a transformation where the triangle seems to have changed in size (it looks like a dilation), while options A, B, and C appear to be translations, rotations, or reflections.

Answer:

D
