Front

What is the result of translating point X(1, 4) 3 units to the left and 9 units down?

Back

X'(-2, -5)

Front

What do we call the point that is to be transformed in geometry?

Back

Pre-Image

Front

What changes when reflecting a point over the y-axis?

Back

The x-coordinate changes sign.

Front

What action is performed when reflecting a shape over an axis?

Back

Flip

Front

What is another term for a turn in geometry?

Back

Rotation

Front

What is the effect of translating a point 5 units to the right and 2 units up?

Back

The new coordinates will be (x+5, y+2).

Front

What is the definition of a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way.

Front

What is the result of reflecting the point (3, 2) over the x-axis?

Back

(3, -2)

Front

What is the difference between a pre-image and an image?

Back

A pre-image is the original figure before transformation, while an image is the result after transformation.

Front

What happens to the coordinates of a point when it is rotated 90 degrees counterclockwise around the origin?

Back

(x, y) becomes (-y, x).
