Rotations

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, known as the center of rotation, by a specified angle in a specified direction.

Front

What does 90° clockwise rotation mean?

Back

It means turning a figure 90 degrees to the right around the center of rotation.

Front

What does 180° counterclockwise rotation mean?

Back

It means turning a figure 180 degrees to the left around the center of rotation.

Front

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

Back

To determine the new position, apply the rotation angle and direction to the coordinates of the point based on 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

If a shape is rotated 90° counterclockwise, how does its orientation change?

Back

The shape will turn to the left, changing its orientation by 90 degrees.

Front

What quadrant does a point in Quadrant I move to after a 180° rotation?

Back

It moves to Quadrant III.

Front

What is the result of rotating a triangle 90° clockwise?

Back

The triangle's vertices will shift positions according to the rotation, resulting in a new orientation.

Front

How can you identify a 90° clockwise rotation visually?

Back

The shape will appear to have turned to the right, with its original base now becoming the new height.

Front

What is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation goes in the direction of a clock's hands, while counterclockwise rotation goes in the opposite direction.
