Rigid Transformations Practice Flashcard

Front

What happens to the coordinates when a point is translated 4 units left?

Back

The x-coordinate decreases by 4.

Front

What is the result of reflecting a point over the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

What transformation is described by rotating a point 90 degrees counterclockwise?

Back

The new coordinates (x, y) become (-y, x).

Front

When a point is reflected over the x-axis, which coordinate changes?

Back

The y-coordinate changes sign.

Front

What are the new coordinates of point C(-6, 2) after a 90-degree counterclockwise rotation?

Back

C' (-2, -6).

Front

If point (-5, 2) is reflected over the y-axis, what are the new coordinates?

Back

(5, 2).

Front

What is the effect of translating a point (x, y) 4 units up?

Back

The new coordinates become (x, y + 4).

Front

Describe the transformation of a point when it is rotated 270 degrees counterclockwise.

Back

The new coordinates (x, y) become (y, -x).

Front

What is the result of reflecting a point over the x-axis?

Back

The y-coordinate changes sign.

Front

How do you determine the new coordinates after a 90-degree clockwise rotation?

Back

The new coordinates (x, y) become (y, -x).
