Intro to Transformations

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way on a coordinate plane.

Front

What are the four main types of transformations?

Back

Translation, Reflection, Rotation, Dilation.

Front

What does a translation do to a figure?

Back

A translation slides a figure from one position to another without changing its shape or size.

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 dilation in geometry?

Back

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

Front

What does a dilation produce?

Back

Dilation produces similar figures.

Front

What happens to the coordinates of a figure during a reflection over the x-axis?

Back

The y-coordinates of the points are inverted (multiplied by -1).

What happens to the coordinates of a figure during a reflection over the y-axis?

Back

The x-coordinates of the points are inverted (multiplied by -1).

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure rotates.
