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

Dilation, Reflection, Rotation, Translation.

Front

What is a dilation?

Back

A dilation is a transformation that resizes an object by a scale factor.

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.

Front

What is a translation?

Back

A translation is a transformation that slides a figure from one position to another without changing its shape or orientation.

Front

What happens during a reflection across the x-axis?

Back

The y-coordinates of the points are inverted, while the x-coordinates remain the same.

What happens during a reflection across the y-axis?

Back

The x-coordinates of the points are inverted, while the y-coordinates remain the same.

Front

How do you perform a 90-degree rotation clockwise?

Back

You turn the figure 90 degrees to the right around the center of rotation.

Front

How do you perform a 180-degree rotation?

Back

You turn the figure 180 degrees around the center of rotation, effectively flipping it upside down.
