Core 8 - 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 does a 90-degree counterclockwise rotation look like?

Back

A 90-degree counterclockwise rotation turns a figure to the left, moving it one quarter of a full turn.

Front

What does a 90-degree clockwise rotation look like?

Back

A 90-degree clockwise rotation turns a figure to the right, moving it one quarter of a full turn.

Front

What is the result of rotating a point (x, y) 90 degrees counterclockwise around the origin?

Back

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

Front

What is the result of rotating a point (x, y) 90 degrees clockwise around the origin?

Back

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

Front

What happens to a figure when it is rotated 180 degrees?

Back

When a figure is rotated 180 degrees, it is turned upside down, resulting in the coordinates changing to (-x, -y).

Front

If Triangle D is rotated 360° clockwise, what is its new position?

Back

The triangle remains in the same position as a 360° rotation brings it back to its original location.

Front

What is the effect of rotating a figure 180 degrees around the origin?

Back

The figure will be flipped to the opposite side of the origin.
