Dilations Quiz

What are the properties of dilations?

• The properties of dilations include a fixed center of dilation, a scale factor that determines the amount of translation or rotation, preservation of size, and the possibility of resulting in a distorted image.

• The properties of dilations include a fixed center of dilation, a scale factor that determines the amount of enlargement or reduction, preservation of shape, and the possibility of resulting in a larger or smaller image.

• The properties of dilations include a fixed center of rotation, a scale factor that determines the amount of enlargement or reduction, preservation of size, and the possibility of resulting in a larger or smaller image.

• The properties of dilations include a variable center of dilation, a scale factor that determines the amount of translation or rotation, preservation of shape, and the possibility of resulting in a distorted image.

What is a similarity transformation?

• A similarity transformation is a transformation that preserves the shape of an object but may change its size or orientation.

• A similarity transformation is a transformation that only changes the size of an object but preserves its shape and orientation.

• A similarity transformation is a transformation that changes the shape of an object but preserves its size and orientation.

• A similarity transformation is a transformation that changes both the shape and size of an object.
