Which transformation is not a rigid motion?O A. Reflecting ABC over the x-axisO B. Dilating ABC by a factor of 2O C. Rotating ABC 90° around the originD. Translating ABC 5 units to the right

Respuesta :

Answer:

B. Dilating ABC by a factor of 2

Explanation:

A transformation is a rigid motion when after the transformation, the distance between the vertex points of the figure is the same as before the transformation. So, reflections, rotations, and translations are considered rigid motion.

On the other hand, when we dilate a figure, the distance between the vertex points change, so it is not a rigid motion. It means that the answer is:

B. Dilating ABC by a factor of 2
