Review of Translations, Reflections, and Rotations 1w/S

Front

Moving a figure to the right

Back

x +

Answer explanation

When translating an image to the right, you increase the x-coordinate of the figure. Therefore, you will add a number to the x value.

Front

Moving a figure down in translation

Back

y -

Answer explanation

When translating an image down, you decrease the y-coordinate. This means you subtract from the y value. Moving down corresponds to y - .

Front

Slide = ?

Back

Translation

Answer explanation

A slide in geometry refers to a translation, which is a type of transformation that moves every point of a shape the same distance in a specified direction, but does not change its size or orientation.

Reflection

Answer explanation

The transformation is a reflection, which flips a figure over a line, creating a mirror image.

Front

Transformation: Reflection

Back

Correct Answer: Reflection

Answer explanation

The transformation is a reflection, which flips a shape over a line, creating a mirror image.

Front

Translate 3 left, 9 down

Back

x'(-4, -5)

Answer explanation

To find x' after translating 3 units left and 9 units down, subtract 3 from the x-coordinate and 9 from the y-coordinate.

If the original point is (−1, 4), then x' becomes (−1−3, 4−9) = (−4, −5).

The correct answer is x'(-4, -5).

Front

Translation of triangle ABC to A'B'C'

Back

down 9, right 4

Answer explanation

Triangle ABC is translated down 9 units and right 4 units to reach triangle A'B'C'.

Front

Axis of reflection

Back

X-axis

Answer explanation

The image is reflected over the X-axis, meaning that points above the X-axis will be mirrored below it, while points below will move above.

Back

Translation

Answer explanation

The transformation described is a translation, which involves moving a shape or object from one location to another without changing its size, shape, or orientation.

Back

Reflection

Answer explanation

The transformation described is a reflection, which flips a shape over a line, creating a mirror image.

This differs from rotation (turning), translation (sliding), and dilation (resizing).
