Geometric Transformations

Front

What is a geometric transformation?

Back

A geometric transformation is a function that moves or changes a shape in a specific way, including translations, rotations, reflections, and dilations.

Front

What are the types of geometric transformations?

Back

The main types of geometric transformations are translation, rotation, reflection, and dilation.

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 are the coordinates of the point (3, -4) reflected over the y-axis?

Back

(-3, -4)

Front

What line does this figure reflect across if the answer is y = -2?

Back

The figure reflects across the line y = -2.

Front

What is the term used to describe the movement of a reflection?

Back

Flip

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.

Front

What word describes the movement of a rotation?

Back

Turn

Front

What are the coordinates of the point (-2, 4) after a rotation 270° counterclockwise about the origin?

Back

(4, 2)

Front

What is a translation in geometry?

Back

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