Reflections and Translations Practice

Front

What is the result of reflecting the point (1, -4) across the x-axis?

Back

(1, 4)

Front

What does a reflection across the y-axis do to the point (4, 1)?

Back

The point becomes (-4, 1).

Front

What is the term for the original figure prior to a transformation?

Back

Pre-image

Front

How do you translate the point P(3, 5) to P' if you move it 2 units to the right and 8 units down?

Back

P' will be (5, -3).

Front

What is the translation needed to move triangle A'B'C' to triangle ABC if A' is at (1, 1) and A is at (3, -2)?

Back

Right two, down three.

Front

What happens to the coordinates of a point when it is reflected across the x-axis?

Back

The y-coordinate changes sign.

Front

What happens to the coordinates of a point when it is reflected across the y-axis?

Back

The x-coordinate changes sign.

Front

If a point is translated 4 units left and 3 units up, what is the new position of the point (2, 2)?

Back

(-2, 5)

Front

What is the effect of translating a figure 5 units down?

Back

All y-coordinates of the figure decrease by 5.

Front

If the point (0, 0) is reflected across both axes, what is the new position?

Back

(0, 0) (it remains the same).
