Geometric Transformations

Front

What is a geometric transformation?

Back

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

Front

What are the four main types of geometric transformations?

Back

Translation, Rotation, Reflection, Dilation.

Front

Which transformation moves every point of a figure the same distance in the same direction?

Back

Translation.

Front

What happens during a translation?

Back

An object is slid from one position to another without changing its shape or orientation.

Front

What is a rotation in geometry?

Back

A rotation is turning a figure around a fixed point, called the center of rotation.

Front

What is the center of rotation?

Back

The fixed point around which a figure is rotated.

Front

What is a reflection in geometry?

Back

A reflection is flipping a figure over a line to create a mirror image.

Front

What is the line of reflection?

Back

The line over which a figure is reflected.

Front

What is dilation in geometry?

Back

Dilation is resizing a figure by a scale factor, either enlarging or reducing it.

Front

What is the scale factor in dilation?

Back

The ratio of the size of the new figure to the size of the original figure.
