Rotations

Rotate 90  Clockwise about the Origin (Same as 270  Counterclockwise) Change the sign of x and switch the order

Rotate 90° clockwise about the origin

Rotate 90  Counterclockwise about the Origin (Same as 270  Clockwise) Change the sign of y and switch the order

Rotate 90° counterclockwise about the origin

Rotate 180  about the Origin ONLY Change the signs

Rotate 180° about the origin

Any figure that can be turned or rotated less than 360° about a fixed point so that the figure looks exactly as it does in its original position. Rotational Symmetry

Ambigrams – Look the same right side up and upside down

Rotational Symmetry in the parking lot

Which figures have rotational symmetry? For those that do, describe the rotation that map the figure onto itself. Regular pentagon Isosceles triangle Rhombus
