Front

When you translate, (x-4 ,y) will move _____.

Back

4 units left

Front

Transformations

Front

Back

Each point translates down 9

Front

What is a rigid transformation?

Back

A transformation that preserves distance and angles, meaning the shape and size of the figure remain unchanged.

Front

What is a translation in geometry?

Back

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

Front

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

Back

The new coordinates will be (-x, y).

Front

What is the effect of a 90-degree rotation counterclockwise on the point (x, y)?

Back

The new coordinates will be (-y, x).

Front

What is the difference between a reflection and a rotation?

Back

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