A rectangle is  sometimes similar to another rectangle, because we can  sometimes  map one onto the other using only dilations and rigid transformations.

Shapes can be mapped to another similar shape by transforming the original shape.

To transform a shape, the following must be true

For a rectangle to be mapped to another, then the corresponding side lengths of the rectangle must be in equivalent ratio

Sometimes, always

Explanation:

A rectangle is  sometimes similar to another rectangle, because we can  always  map one onto the other using only dilations and rigid transformations. A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

A dilation is NOT referred to as a rigid transformation (or isometry) because the image is NOT necessarily the same size as the pre-image (and rigid transformations preserve length).

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
