Question

1. here are 4 triangles that have each been transformed by a different transformation. which transformation is not a rigid transformation? (from unit 1, lesson 10.)

Explanation:

A rigid transformation preserves the size and shape of a figure. This includes translations (sliding), rotations (turning), and reflections (flipping). Dilation is a non - rigid transformation as it changes the size of the figure. In the given options, we need to identify the transformation that changes the size. Option A appears to be a rotation, Option B a translation, Option C a reflection. Option D shows a change in the size of the triangle, which is a non - rigid transformation (dilation).

Answer:

D
