Module 2 Review: Rigid Transformations

Front

What is a rigid transformation?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure. Examples include translations, rotations, and reflections.

Front

What happens to the coordinates of a point when it is translated 4 units left and 5 units down?

Back

The new coordinates are found by subtracting 4 from the x-coordinate and 5 from the y-coordinate.

Front

What are the coordinates of Point A' if Point A is at (4, 5) and it is translated 4 units left and 5 units down?

Back

The new coordinates are (0, 0).

Front

What is the direction of the x-axis?

Back

The x-axis is horizontal.

Front

What is the direction of the y-axis?

Back

The y-axis is vertical.

Front

What is a translation in geometry?

Back

A translation is a type of transformation that moves every point of a figure the same distance in the same direction.

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 rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

Identify the transformation: A figure is flipped over the y-axis. What is this transformation called?

Back

Reflection across the y-axis.

Front

Identify the transformation: A figure is turned 90 degrees counterclockwise around a point. What is this transformation called?

Back

Rotation.
