TRANSFORMATION RULES

Front

What is a reflection in geometry?

Back

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

Front

What is a translation in geometry?

Back

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

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, known as the center of rotation, by a certain angle.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.

Front

Identify the transformation: A triangle moves 5 units to the right and 3 units up.

Back

Translation.

Front

Identify the transformation: A square is flipped over the x-axis.

Back

Reflection.

Front

Identify the transformation: A rectangle is turned 90° counterclockwise around its center.

Back

Rotation.

Front

Identify the transformation: A circle is enlarged by a scale factor of 2.

Back

Dilation.

Front

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

Back

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

Front

What is the effect of a translation of (x, y) by (3, -2)?

Back

The new coordinates will be (x+3, y-2).
