Intro to Transformations

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 from one position to another without turning it.

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 rotation?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is a dilation?

Back

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

Front

What does congruent mean in terms of transformations?

Back

Congruent means that two figures have the same shape and size after a transformation.

Front

What is the original figure before a transformation called?

Back

The original figure is called the pre-image.

Front

What is the figure after a transformation called?

Back

The figure after a transformation is called the image.

Front

How does a translation affect the size of a figure?

Back

A translation does not change the size of a figure; it remains congruent.
