Transformations

Front

What is a transformation in geometry?

Back

A transformation is a change in the position, size, or shape of a figure.

Front

What are the four main types of transformations?

Back

Translation, Reflection, Rotation, Dilation.

Front

What does it mean to translate a figure?

Back

To translate a figure means to slide it in a straight line from one position to another without changing its shape or size.

Front

What happens to the coordinates of a point during a translation?

Back

The coordinates change based on the direction and distance of the translation.

Front

What is a reflection in geometry?

Back

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

Front

What line is used for reflection?

Back

The line used for reflection is called the line of reflection.

Front

What does it mean to rotate a figure?

Back

To rotate a figure means to turn it around a fixed point, called the center of rotation.

Front

What is the angle of rotation?

Back

The angle of rotation is the degree measure of the turn applied to the figure.

Front

What is dilation in geometry?

Back

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

Front

What is the scale factor in dilation?

Back

The scale factor is the ratio of the size of the image to the size of the original figure.
