Angle Rotations (Standard Position)

Recall what it means for an angle to be drawn in standard position. The applet below helps illustrate the difference between angles with positive measure (positive orientation) versus angles with negative measure (negative orientation). Interact with the applet for a couple of minutes. Then answer the questions that follow.

1.

How can you tell if an angle (drawn in standard position within the coordinate plane) has a positive measure (positive orientation)? Explain.

2.

How can you tell if an angle (drawn in standard position within the coordinate plane) has a negative measure (negative orientation)? Explain.
