Identify Transformations

Front

What is a transformation in geometry?

Back

A transformation 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

Translation, Rotation, Reflection, Dilation.

Front

What is translation?

Back

Translation is a transformation that slides a shape from one position to another without turning or flipping it.

Front

What is rotation?

Back

Rotation is a transformation that turns a shape around a fixed point, called the center of rotation.

Front

What is reflection?

Back

Reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

What is dilation?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

Front

What does it mean to rotate a shape 90 degrees counterclockwise?

Back

It means to turn the shape 90 degrees to the left around a fixed point.

Front

How can you identify a translation?

Back

A translation can be identified by the same shape appearing in a different location without any changes in size or orientation.

Front

What is the effect of a reflection across the x-axis?

Back

A reflection across the x-axis flips the shape over the x-axis, changing the sign of the y-coordinates.

What is the effect of a reflection across the y-axis?

Back

A reflection across the y-axis flips the shape over the y-axis, changing the sign of the x-coordinates.
