Transformations Review

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

What is a translation?

Back

A translation is a transformation that slides a figure in a straight line from one position to another without changing its size or shape.

Front

What is a rotation?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation.

Front

What is a reflection?

Back

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

Front

What is a dilation?

Back

A dilation is a transformation that changes the size of a figure but keeps its shape the same, using a scale factor.

Front

What does the scale factor in a dilation represent?

Back

The scale factor represents how much larger or smaller the figure will be after the dilation.

Front

What is the effect of a scale factor greater than 1 in a dilation?

Back

A scale factor greater than 1 enlarges the figure.

Front

What is the effect of a scale factor less than 1 in a dilation?

Back

A scale factor less than 1 reduces the size of the figure.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is flipped to create a mirror image.
