Flag semaphore is a way to use flags to signal messages. The diagrams show how to signal the letters Z and J in the semaphore alphabet. For each, precisely describe a rotation that would take the left-hand flag (L) to the right-hand flag (R).

Quadrilateral A B C D and points R and Q plotted on square grid. Point R is one unit to the left of Point A. Point Q is one unit below Point A. A B and C D are both 3 units long.
Quadrilateral H J K L M N and Points P and O on an isometric grid. Points O and P are below and to the right of the Quadrilateral. Points O, N and K are on the same diagonal grid line. Points M, L and P are on the same vertical grid line.

Draw each image, and determine the angle of rotation needed for these steps to take
The three rigid motions are reflect, translate, and rotate. Each of these rigid motions can be applied to any figure to create an image that is congruent. To do a rotation, we need to know three things: the center, the direction, and the angle.
