Multiple Choice
Triangle ABC was transformed using the rule (x, y) → (–y, x). Assuming the rotation was counterclockwise. The vertices of the triangles are shown.

Which best describes the transformation?
The transformation was a 90° rotation about the origin
The transformation was a 180° rotation about the origin.
The transformation was a 270° rotation about the origin.
The transformation was a 360° rotation about the origin.

Graphing
Plot the image after a rotation of 180 degrees.

Symmetry
When an object is exactly the same as another object even if it is moved, rotated or flipped.
Lots of real-world examples.
"Fold" the object in half and have it perfectly overlap. (oddly-satisfying!)

Rotational Symmetry
When you rotate an object and it looks exactly the same.
Order of rotation: the number of times a object looks the same as it is being rotated 360 degrees (in a circle).
Magnitude of rotation: the angle of rotation in which the object looks the same as it goes around in a circle.
