Translations and Reflections

Front

What does a translation do to a figure on the coordinate plane?

Back

Slides it

Front

What is the algebraic representation of translating a figure 3 units left and 5 units down?

Back

(x-3, y-5)

Front

Determine the rule used to translate quadrilateral EFGH to E'F'G'H'. If the translation is (x - 3, y - 6), what does this mean?

Back

The figure is moved 3 units to the left and 6 units down.

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 happens to the coordinates of a point (x, y) when it is reflected over the x-axis?

Back

The new coordinates become (x, -y).

Front

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

Back

The new coordinates become (-x, y).

Front

If a figure is translated 4 units right and 2 units up, what is the algebraic representation?

Back

(x + 4, y + 2)

Front

Describe the translation that moved ABCD to A'B'C'D'. If it moved 6 units left and 3 units up, what is the algebraic representation?

Back

(x - 6, y + 3)

Front

What is the effect of translating a figure 0 units left/right and 0 units up/down?

Back

The figure remains unchanged.

Front

If a point (2, 3) is reflected over the x-axis, what are the new coordinates?

Back

(2, -3)
