Rotations- degrees

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 specified 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 does a 90-degree clockwise rotation look like?

Back

A 90-degree clockwise rotation turns the figure 1/4 of the way around the center of rotation in a clockwise direction.

Front

What does a 90-degree counterclockwise rotation look like?

Back

A 90-degree counterclockwise rotation turns the figure 1/4 of the way around the center of rotation in a counterclockwise direction.

Front

What is a 180-degree rotation?

Back

A 180-degree rotation turns the figure halfway around the center of rotation, resulting in an upside-down version of the original figure.

Front

What is a 270-degree counterclockwise rotation?

Back

A 270-degree counterclockwise rotation turns the figure 3/4 of the way around the center of rotation in a counterclockwise direction.

Front

What is the difference between clockwise and counterclockwise rotations?

Back

Clockwise rotation moves in the same direction as the hands of a clock, while counterclockwise rotation moves in the opposite direction.

Front

If a triangle is rotated 90 degrees clockwise, where will its vertices move?

Back

The vertices will move to new positions based on the 90-degree clockwise rotation around the center of rotation.

Front

How do you determine the new position of a figure after rotation?

Back

To determine the new position, visualize or use a coordinate system to apply the rotation angle to each vertex of the figure.
