Rotations

Front

What is a rotation in geometry?

Back

A rotation in geometry is a transformation that turns a figure around a fixed point, known as 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

What is the angle of rotation?

Back

The angle of rotation is the measure of the degree through which a figure is rotated around the center of rotation.

Front

What direction is a counterclockwise rotation?

Back

A counterclockwise rotation is a rotation that moves in the opposite direction of the hands of a clock.

Front

What direction is a clockwise rotation?

Back

A clockwise rotation is a rotation that moves in the same direction as the hands of a clock.

Front

How many degrees are in a full rotation?

Back

There are 360 degrees in a full rotation.

Front

What is the result of rotating a figure 90 degrees clockwise?

Back

Rotating a figure 90 degrees clockwise results in a new position of the figure that is turned 90 degrees to the right around the center of rotation.

Front

What is the result of rotating a figure 270 degrees counterclockwise?

Back

Rotating a figure 270 degrees counterclockwise is equivalent to rotating it 90 degrees clockwise.

Front

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

Back

To determine the new coordinates of a point after a rotation, apply the rotation rules based on the angle and direction of rotation to the original coordinates.

Front

What is the relationship between clockwise and counterclockwise rotations?

Back

Clockwise and counterclockwise rotations are opposite directions; a clockwise rotation can be converted to a counterclockwise rotation by subtracting from 360 degrees.
