Translations & Reflections

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 is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in a specified direction.

Front

What happens to the coordinates of a point (x, y) when it is translated 6 units up?

Back

The new coordinates will be (x, y + 6).

Front

What is the effect of reflecting a figure across the x-axis?

Back

The y-coordinates of the points of the figure change sign, resulting in a mirror image across the x-axis.

Front

How do you identify a translation from one figure to another?

Back

By determining the direction and distance each point of the figure has moved.

Front

What is the result of reflecting a point (3, 4) across the y-axis?

Back

The new coordinates will be (-3, 4).

Front

If a quadrilateral is translated 6 units down and 3 units left, what are the new coordinates of point (5, 7)?

Back

The new coordinates will be (2, 1).

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a figure around a point, while a reflection flips it over a line.

Front

What does it mean to reflect a figure across the y-axis?

Back

It means that for every point (x, y), the new point will be (-x, y).

Front

If triangle ABC is translated to triangle A'B'C', how can you describe the transformation?

Back

Identify the direction and distance each vertex has moved.
