Transformations on Coordinate Plane

Front

Reflections over the x-axis change ______________.

Back

the sign of the y-coordinate.

Front

Identify the transformation from ABCD to A'B'C'D'.

Back

Reflection across the y-axis.

Front

Translate C(-6, 2) and B(-1, -1) using (x, y) -> (x - 1, y - 3). What are the new coordinates?

Back

C' (-7, -1), B' (-2, -4).

Front

Identify the transformation from ABC to A'B'C'. What is the transformation if the coordinates change to (x+8, y+4)?

Back

(x+8, y+4).

Front

What are the new coordinates of A(-2, 2) and B(3, 2) after a 180-degree rotation?

Back

A' (2, -2), B' (-3, -2).

Front

What is a transformation in geometry?

Back

A transformation is a function that maps a set of points to another set of points, changing their position or orientation.

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 does a translation do to a figure?

Back

A translation moves a figure from one location to another without changing its shape or orientation.

Front

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

Back

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

Front

What is the effect of a reflection over the y-axis on a point (x, y)?

Back

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