Transformations Introduction

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 three main types of transformations?

Back

Translation (Slide), Rotation (Turn), Reflection (Flip).

Front

What happens to the size of a figure during a translation?

Back

The size of the figure remains the same.

Front

What is a translation?

Back

A translation is a transformation that moves every point of a shape the same distance in the same direction.

Front

What is a rotation?

Back

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

Front

What is a reflection?

Back

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

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but not its shape.

Front

What does a scale factor of 1/2 mean in dilation?

Back

It means the new figure will be half the size of the original figure.

Front

What is the effect of a 360-degree rotation on a shape?

Back

A 360-degree rotation returns the shape to its original position.

Front

What is the effect of a 180-degree rotation on a shape?

Back

A 180-degree rotation turns the shape upside down.
