Which of the following describes a rigid motion transformation?

a. enlarging a photo
b. spinning a spinner
c. filling a tire with air
d. slicing a log into sections

B. Spinning a spinner

Step-by-step explanation:

A rigid transformation does not change the size or shape of the object ,that is why it is called a rigid motion. The object just moves, but remains the same.

So, as per definition, option B is the answer.

Enlarging a photo will increase its size. Filling a tire with air will also make the tire bigger. And slicing the log in sections will overall decrease the log size.

But only a spinner will remain the same in size, no matter how many times it is spins.

So, Option B is correct.

i dont get

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
