Front

What are the new coordinates of point Q (-8, -6) after reflecting across the y-axis?

Back

(8, -6)

Front

What translation maps A (-4,1) to A’ (-1,3)?

Back

T(x+3, y+2)

Front

Where is point A' if point A (2, 5) is rotated 180 degrees?

Back

(-2, -5)

Front

Where is point F' if point F (-1, 3) is rotated -90 degrees?

Back

(3, 1)

Front

What is a transformation in geometry?

Back

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

Front

What does reflecting a point across the y-axis do to its coordinates?

Back

The x-coordinate changes sign, the y-coordinate remains the same.

Front

What is the effect of a 180-degree rotation on a point's coordinates?

Back

Both coordinates change signs.

Front

What does the notation T(x+2, y+3) represent?

Back

A translation that moves a point 2 units right and 3 units up.

Front

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

Back

The new coordinates are (-y, x).
