Which of the following describes a rigid motion transformation?A.Dilating a pictureB.Enlarging the size of a parking spotC.Slicing a sandwich into 4 piecesD.Hitting a tennis ball over a net

A rigid motion transformation, also known as an isometry, is a transformation that preserves distance and angles, so it does not change the shape or size of the figure. It only changes the position or orientation of the figure.

Looking at the options:

A. Dilating a picture - This involves changing the size of the picture, so it's not a rigid motion transformation.

B. Enlarging the size of a parking spot - This also involves changing the size, so it's not a rigid motion transformation.

C. Slicing a sandwich into 4 pieces - This involves changing the shape of the sandwich, so it's not a rigid motion transformation.

D. Hitting a tennis ball over a net - This involves changing the position of the ball without changing its shape or size, so this is a rigid motion transformation.

So, the answer is D. Hitting a tennis ball over a net.
