- With this tool you can create angles in different ways (also see command Angle):
- Click on three points to create an angle between these points. The second point selected is the vertex of the angle.
- Click on two segments to create the angle between them.
- Click on two lines to create the angle between them.
- Click on two vectors to create the angle between them.
- Click on a polygon to create all angles of this polygon.

- Note: If the polygon was created by selecting its vertices in counter clockwise orientation, the
*Angle*tool gives you the interior angles of the polygon.

**Note:**Angles are created in*counter clockwise*orientation. Therefore, the order of selecting these objects is relevant for the*Angle*tool. If you want to limit the maximum size of an angle to 180°, un-check*Allow Reflex Angle*on tab*Basic*of the Properties Dialog.
