Front

What symbol represents 2 moves in a Transformation?

Back

'' (double prime) represents 2 moves in a Transformation.

Front

What are the new vertices A', B', and C' after rotating triangle ABC with vertices A(-2, 1), B(2, 4), and C(4, 2) 90° clockwise?

Back

A'(1, 2), B'(4, -2), and C'(2, -4) are the new vertices after the rotation.

Front

In which direction does a figure move when rotated Counter-Clockwise?

Back

A figure moves from left to right when rotated Counter-Clockwise.

Front

How many turns on a coordinate plane is equivalent to 360 degrees?

Back

360 degrees is equivalent to 1 turn on a coordinate plane.

Front

What is the image of the point (-1,-2) when rotated around the origin 180 degrees?

Back

The image of the point (-1,-2) after a 180-degree rotation is (1, 2).

Front

Define rotation in geometry.

Back

Rotation is a transformation that turns a figure around a fixed point, called the center of rotation.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure is rotated.

Front

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

Back

The new coordinates after a 90-degree clockwise rotation are (y, -x).

Front

What happens to the coordinates of a point (x, y) after a 180-degree rotation?

Back

The new coordinates after a 180-degree rotation are (-x, -y).

Front

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

Back

The new coordinates after a 90-degree counter-clockwise rotation are (-y, x).
