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, Reflection, Rotation, and Dilation.

Front

Define Translation.

Back

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

Front

What is Reflection?

Back

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

Front

What does Rotation mean in geometry?

Back

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

Front

What is Dilation?

Back

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

Front

How do you identify a Translation?

Back

A translation can be identified by the same shape appearing in a different location without any rotation or reflection.

Front

What is the algebraic notation for a Reflection across the y-axis?

Back

(x, y) → (-x, y)
