Front

Describe the transformation: (x, y) -> (x-2, y+7)

Back

Translation 2 units to the left & 7 units up.

Front

Determine how to translate triangle A'B'C' from triangle ABC.

Back

(x-2, y+9)

Front

Point W is located at (7, 3) on a coordinate plane. Point W is translated 2 units to the left and 3 units up. What are the coordinates of the image point W′?

Back

(5, 6)

Front

What is a mirror image of a figure called?

Back

Reflection.

Front

Which transformation involves flipping a figure over a line?

Back

Reflection.

Front

What is the result of rotating a figure 90 degrees clockwise around the origin?

Back

The coordinates (x, y) become (y, -x).

Front

What is the transformation that moves every point of a figure the same distance in the same direction?

Back

Translation.

Front

If a triangle is reflected across the x-axis, what happens to the y-coordinates of its vertices?

Back

The y-coordinates change sign.

Front

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

Back

The point becomes (-x, -y).

Front

What is the transformation that turns a figure around a fixed point?

Back

Rotation.
