Rotations Practice

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 degrees clockwise rotation mean?

Back

A 90 degrees clockwise rotation means turning the figure 90 degrees to the right around the center of rotation.

Front

What does a 180 degrees rotation do to a figure?

Back

A 180 degrees rotation flips the figure to the opposite side, effectively turning it upside down.

Front

What is the result of a 270 degrees clockwise rotation?

Back

A 270 degrees clockwise rotation is equivalent to a 90 degrees counterclockwise rotation.

Front

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

Back

The vertices will move to new positions that are 90 degrees to the right of their original locations.

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

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

Back

To determine the new position, apply the rotation angle to the coordinates of the point using rotation formulas.

Front

What is the rotation formula for a point (x, y) rotated 90 degrees clockwise?

Back

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