Question

Which statement explains if a dilation was applied? A dilation was applied to the fabric because the width of the fabric was preserved. A dilation was applied to the fabric because the angle measures were preserved. A dilation was not applied to the fabric because the angle measures are the same. A dilation was not applied to the fabric because the length was changed, not the width.

Answer 1

Answer:  A dilation was applied to the fabric because the angle measures were preserved.

Step-by-step explanation:

• A dilation is a transformation that creates an image that is the exactly same shape as the original but have a different size.
• It preserves the angles of the figure.
• It does not preserve the side length of the figure.

Let's check the given statement:

If any side-length of the fabric was preserved then it's not dilation, so first statement is wrong.

By the definition of dilation, it preserves the angles of the figure  so the second statement is correct.

Also, third and fourth statements are wrong by the definition of dilation.

Hence, the correct answer is " A dilation was applied to the fabric because the angle measures were preserved.".
