Question 9: Please help, what would be the length of the image of the segment GH?

The length of the image of the segment GH would be 5 units.

Explanation:

You can use the center of dilation as your origin of coordintes.

Thus, the point H would have coordinates (0,0) and the point G (-1,0).

A dilation multiplies the coordinates by the scale factor. Hence:

H = (0,0) → H' = 5 × (0,0) = (0,0)G = (-1,0) → G] = 5 × (-1, 0) = (-5, 0)

Thus, the length of the image of segment GH would be the distance from 0 to -5 in a number line, which is 5.

)because it's going in order of the math sign

This is what i found “answer: a rigid transformation preserves both the side lengths and the angle measures of a polygon. step-by-step explanation: rigid transformations are the transformations which does not affect the size and the shape of figure .” i hope this you for what your looking for. can you plz mark me brainliest?
