Question

A line segment has a length of 9 units. After a certain transformation is applied to the segment, the new segment has
a length of 9 units. What was the transformation?

Answer 1

Answer:

Not dilation

Step-by-step explanation:

Well, it isn't dilation.

I'm not sure the context of the problem, but there are four types of transformation.

1. Dilation

2. Reflection

3. Rotation

4. Translation

Example of those are in the jpg.

If the line segment has the same length both times, it cannot be dilation.

I'm not sure about which specific one it is, but dilation is the only one that changes size.

Hope this could somewhat help :)
