Back

4 units left

Front

What is this picture an example of? (Choose from: Reflection, Translation, Rotation, Dilation)

Back

Rotation

Front

Identify the transformation from ABC to A'B'C'. (Choose from: 90° clockwise rotation, 90° counter clockwise rotation, Reflection across the y-axis, Reflection across the x-axis)

Back

Reflection across the x-axis

Front

What is a transformation in geometry?

Back

A change in the position, size, or shape of a figure.

Front

Define translation in geometry.

Back

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

Front

What happens to the coordinates of a point (x, y) when it is translated 3 units up?

Back

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

Front

What is a reflection in geometry?

Back

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

Front

How do you perform a reflection across the y-axis?

Back

Change the sign of the x-coordinate: (x, y) becomes (-x, y).
