Rotations

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle in a specific direction.

Front

What is the center of rotation?

Back

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

Front

How many degrees are in a full rotation?

Back

A full rotation is 360 degrees.

Front

What is a 90-degree clockwise rotation?

Back

A 90-degree clockwise rotation turns a figure 90 degrees to the right around the center of rotation.

Front

What is a 90-degree counterclockwise rotation?

Back

A 90-degree counterclockwise rotation turns a figure 90 degrees to the left around the center of rotation.

Front

What happens to the coordinates of a point (x, y) after a 90-degree clockwise rotation?

Back

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

Front

What happens to the coordinates of a point (x, y) after a 90-degree counterclockwise rotation?

Back

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

Front

What is a 180-degree rotation?

Back

A 180-degree rotation turns a figure halfway around the center of rotation, resulting in the figure being upside down.

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

Back

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

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.
