Transformations!

Front

What is a transformation in geometry?

Back

A transformation in geometry is an operation that moves or changes a shape in some way to produce 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 moves every point of a shape the same distance in a given direction.

Front

How do you write a rule for a translation?

Back

A rule for a translation can be written in the form (x + a, y + b), where 'a' and 'b' are the distances moved in the x and y directions, respectively.

Front

What is a rotation?

Back

A rotation is a transformation that turns a figure about a fixed point, known as 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 the line of reflection?

Back

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

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.

Front

What is the scale factor in dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

Front

How do you identify a translation on a graph?

Back

A translation can be identified on a graph by observing that all points of the figure move the same distance in the same direction.
