Question

7-2: similarity transformations
word/concept definition
similarity transformation
a composition of ____ or __________ rigid transformations and a
__________.

• results in an image that is similar to the preimage.
• all figures are similar

Explanation:

A similarity transformation combines rigid transformations (which preserve size and shape) and a dilation (which changes size but preserves shape). Rigid transformations include translations, rotations, and reflections, so the first two blanks can be filled with examples of these. The transformation produces an image similar to the preimage, and all circles are a common example of figures that are always similar.

Answer:

1. First blank: translation
2. Second blank: rotation
3. Third blank: dilation
4. Fourth blank (already written, confirmed): similar
5. Fifth blank (already written, confirmed): circles
