d

Front

Determine where X' would be if you translated X 3 units to the left and 9 units down. What are the new coordinates?

Back

(-4, -5)

Front

Point (-5,2) is reflected over the y axis. Where is the new point located?

Back

(5,2)

Front

Describe the transformation: translation: right 3 and down 2, reflection across y=-x, rotation 180 degrees about the origin, rotation 90 degrees clockwise about the origin.

Back

rotation 180 degrees about the origin

Front

What is a translation in geometry?

Back

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

Front

What does it mean to reflect a point over the y-axis?

Back

To reflect a point over the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same.

Front

What is the result of rotating a point 90 degrees clockwise about the origin?

Back

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

Front

What is the difference between a rotation and a reflection?

Back

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

Front

If point A(2, 3) is translated 4 units left and 2 units up, what are the new coordinates?

Back

(-2, 5)
