Question

flipping a figure over a line to produce a mirror image is known as _. resizing a figure by a scale factor while maintaining its shape is called _. the ratio of the lengths of corresponding sides of two similar figures is called the _. to confirm similarity, one figure must be a _ of the other. a _ moves a figure without changing its shape or size.

Explanation:

1. Flipping a figure over a line to get a mirror - image is reflection, a common geometric transformation.
2. Resizing a figure by a scale factor while keeping its shape is dilation.
3. The ratio of corresponding - side lengths of similar figures is the scale factor.
4. For figures to be similar, one must be a dilation of the other.
5. A translation moves a figure without changing shape or size.

Answer:

1. Reflection
2. Dilation
3. Scale factor
4. Dilation
5. Translation
