What are congruence transformations?

Back

Transformations that preserve the shape and size of a figure, including rotations, translations, and reflections.

Front

List the three types of congruence transformations.

Back

Rotations, Translations, Reflections.

Front

What is a rotation in geometry?

Back

A transformation that turns a figure around a fixed point, called the center of rotation.

Front

What is a translation in geometry?

Back

A transformation that slides a figure from one position to another without turning it.

Front

What is a reflection in geometry?

Back

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

Front

What does it mean to reflect a figure over the x-axis?

Back

To flip the figure over the x-axis, changing the sign of the y-coordinates of the points.

Front

What does it mean to reflect a figure over the y-axis?

Back

To flip the figure over the y-axis, changing the sign of the x-coordinates of the points.

Front

What is the effect of translating a figure 5 units to the right and 3 units up?

Back

The x-coordinates increase by 5 and the y-coordinates increase by 3.

Front

What is the sequence of transformations?

Back

The order in which multiple transformations are applied to a figure.

Front

How does the order of transformations affect the final image?

Back

The final image can be different depending on the order in which transformations are applied.
