Transformation Test Lessons 1-6 Review

Front

What is translation in geometry?

Back

Translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What is reflection in geometry?

Back

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

Front

What is rotation in geometry?

Back

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

Front

What happens to the coordinates of a point (x, y) when it is rotated 90 degrees clockwise about the origin?

Back

The coordinates change to (y, -x).

Front

What happens to the coordinates of a point (x, y) when it is reflected over the y-axis?

Back

The coordinates change to (-x, y).

Front

What is the result of 5⁻² / 5⁻⁴?

Back

The result is 5².

Front

What is the effect of a 180-degree rotation on a point (x, y)?

Back

The coordinates change to (-x, -y).

Front

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

Back

The coordinates change to (-y, x).

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is reflected to create a mirror image.

Front

What is the difference between a clockwise and counterclockwise rotation?

Back

Clockwise rotation moves in the direction of a clock's hands, while counterclockwise rotation moves in the opposite direction.
