Adilation with center (0,0) and scale factor "k" is applied to a polygon. what dilation can you apply to the image to return it to the original preimage?

So when we scale up this image, all points' distances from the center are multiplied by . We want to then put them back to where they were before.

Thinking about inverse operations, we could just divide by as , then the opposite reciprocal would be

Iwould say they are complementary because that’s the division of a 90 degree angle and it’s split between the middle of them

When i did the math i got 11 cm
