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 specified 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 is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation moves in the same direction as the hands of a clock, while counterclockwise rotation moves in the opposite direction.

Front

If a triangle is rotated 90 degrees clockwise, what is the new orientation of the triangle?

Back

The triangle will be turned 90 degrees to the right from its original position.

Front

What happens to the coordinates of a point (x, y) when it is rotated 90 degrees clockwise around the origin?

Back

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

Front

What happens to the coordinates of a point (x, y) when it is rotated 180 degrees around the origin?

Back

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

Front

If Triangle A is rotated 90° clockwise, how can we determine the new position of the triangle?

Back

By applying the rotation transformation to each vertex of Triangle A and plotting the new coordinates.

Front

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

Back

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

Front

How do you identify the new location of a triangle after rotation?

Back

By applying the rotation rules to each vertex and comparing the new coordinates to the original figure.
