Transformations Review

Front

What is dilation in transformations?

Back

Dilation is a transformation that produces an image that is the same shape as the original but is a different size.

Front

How many quadrants are in a coordinate plane?

Back

There are 4 quadrants in a coordinate plane.

Front

What transformation is described as a change in size of a figure?

Back

Dilation.

Front

What is a rotation in transformations?

Back

A rotation is a transformation that turns a figure about a fixed point.

Front

What is a translation in transformations?

Back

A translation is a transformation that slides a figure from one position to another without turning it.

Front

What is a reflection in transformations?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What does it mean for a transformation to be rigid?

Back

A rigid transformation is one that preserves the shape and size of a figure, such as translations, rotations, and reflections.

Front

What is the center of dilation?

Back

The center of dilation is a fixed point in the plane about which all points are expanded or contracted.

Front

What is the scale factor in dilation?

Back

The scale factor is the ratio of the distance from the center of dilation to a point on the image and the distance from the center of dilation to the corresponding point on the original figure.

Front

How does a dilation affect the coordinates of a point?

Back

In dilation, the coordinates of a point are multiplied by the scale factor.
