Transformations

Front

What are the three types of transformations in geometry?

Back

Translations, rotations, and reflections.

Front

What is a transformation that moves a shape without changing its size or orientation?

Back

Translation.

Front

What is the transformation that flips a shape over a line?

Back

Reflection.

Front

What is the transformation that turns a shape around a fixed point?

Back

Rotation.

Front

How does a translation affect the coordinates of a shape?

Back

It adds a constant value to the x and/or y coordinates.

Front

What is the effect of a reflection over the x-axis on the coordinates (x, y)?

Back

The new coordinates will be (x, -y).

Front

What is the effect of a 90-degree rotation counterclockwise on the coordinates (x, y)?

Back

The new coordinates will be (-y, x).

Front

What is the effect of a reflection over the y-axis on the coordinates (x, y)?

Back

The new coordinates will be (-x, y).

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a shape around a point, while a reflection flips it over a line.

Front

What is the term for the distance a shape is moved during a translation?

Back

Vector.
