Translations and Reflections Review

Front

What is a reflection in geometry?

Back

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

Front

What are the coordinates of the reflection of point (6, -3) over the x-axis?

Back

(6, 3)

Front

If a point S(3, 7) is reflected across the y-axis, what are the new coordinates?

Back

S'(-3, 7)

Front

What is the translation rule for moving point M(-3, 5) to M' using (x, y) → (x - 1, y)?

Back

M' is (-4, 5).

Front

What is the translation rule that moves a point 2 units to the right and 6 units down?

Back

(x + 2, y - 6)

Front

What is the difference between translation and reflection?

Back

Translation moves a figure without changing its orientation, while reflection flips it over a line.

Front

How do you reflect a point over the y-axis?

Back

Change the sign of the x-coordinate.

Front

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

Back

The y-coordinate changes sign.

Front

If triangle ∆ABC has vertices A(1, 2), B(3, 4), and C(5, 6), what are the coordinates after reflecting over the x-axis?

Back

A'(1, -2), B'(3, -4), C'(5, -6).

Front

What is the result of translating point (2, 3) using the rule (x + 3, y - 1)?

Back

(5, 2)
