Respuesta :
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).
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
- The shapes must be similar
- The shapes must be the same type
- The shapes must have corresponding side lengths
For a rectangle to be mapped to another, then the corresponding side lengths of the rectangle must be in equivalent ratio
