Tranformation Practice Test

Front

What happens to the point (x-4, y) when translated?

Back

The point moves 4 units left.

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

If a point is translated 4 units left and 4 units up, what is the new position of the point (x, y)?

Back

The new position is (x-4, y+4).

Front

What is the rule for reflecting a point across the line x = 3?

Back

To reflect a point (x, y) across x = 3, the new x-coordinate is 6 - x, while the y-coordinate remains the same.

Front

What does it mean to translate a point in geometry?

Back

To translate a point means to move it a certain distance in a specified direction without changing its orientation.

Front

Identify the transformation: A shape is flipped over the y-axis.

Back

This is a reflection across the y-axis.

Front

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

Back

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

Front

What is the transformation rule for translating a point 5 units right and 1 unit down?

Back

The new position of the point (x, y) will be (x+5, y-1).

Front

How do you determine if a transformation is a reflection?

Back

A transformation is a reflection if the pre-image and image are mirror images across a line.

Front

What is the result of reflecting a point (2, 5) across the line y = -3?

Back

The new coordinates will be (2, -11).
