Rotations

Front

What is the result of rotating a point (x, y) 180° about the origin?

Back

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

Front

If point A is at (3, 5), what are the coordinates of A' after a 180° rotation about the origin?

Back

A' will be at (-3, -5).

Front

What is the definition of a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What is the image in the context of transformations?

Back

The image is the new figure created from a transformation.

Front

How do you reflect a point (x, y) over the y-axis?

Back

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

Front

What are the coordinates of point C (3, 2) after reflecting over the y-axis?

Back

C' will be at (-3, 2).

Front

What does it mean to translate a figure in geometry?

Back

To translate a figure means to slide it in a straight line without rotating or flipping it.

Front

If trapezoid ABCD is translated 8 units down and 5 units to the right, what is the transformation rule for point A (x, y)?

Back

The new coordinates will be (x + 5, y - 8).

Front

What is the difference between rotation and reflection in geometry?

Back

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

Front

What is the rule for rotating a point 90° clockwise about the origin?

Back

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