Slide the**BEARING**slider to change the bearing from point*A*to point*B*. You can also move any of the 3 points around at any time. Then, answer the questions that follow.## 1.

In words, describe what the bearing from point *A* to point *B *means. Be sure to be detailed in your description!

## 2.

Can you give another bearing equivalent to a bearing of 120 degrees? Why is this?

## 3.

If point *B* is directly south of *A*, what is point *B*'s bearing from *A*?

## 4.

If point *B* is directly west of *A*, what is point *B*'s bearing from *A*?
