FLASHCARD QUESTION

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure is rotated. In most cases, it is the origin (0,0) on the coordinate plane.

FLASHCARD QUESTION

Front

How do you rotate a point 90 degrees clockwise?

Back

To rotate a point (x, y) 90 degrees clockwise, the new coordinates will be (y, -x).

4.

FLASHCARD QUESTION

Front

How do you rotate a point 90 degrees counterclockwise?

Back

To rotate a point (x, y) 90 degrees counterclockwise, the new coordinates will be (-y, x).

FLASHCARD QUESTION

Front

What are the coordinates of point B(1, -8) after a 90-degree clockwise rotation?

Back

The coordinates of point B after a 90-degree clockwise rotation are (-8, -1).

FLASHCARD QUESTION

Front

What is the result of rotating a point 180 degrees?

Back

Rotating a point (x, y) 180 degrees results in the coordinates (-x, -y).

7.

FLASHCARD QUESTION

Front

If a point remains unchanged after rotation, what degree of rotation has occurred?

Back

If a point remains unchanged after rotation, it has undergone a 360-degree rotation.
