What do you know about the exterior angles of a triangle?

1. Each exterior angle forms a linear pair with its adjacent interior angle.

2. In other words, each exterior angle + adjacent interior angle = 180 degrees

3. Exterior angle = Sum of the two remote interior angles.

4. In other words, an exterior angle = sum of the non-adjacent interior angles.

5. In any regular convex polygon, exterior angles always add to 360 degrees.

6. In any regular convex polygon, each exterior angle = 360/number of sides.

7. You can extend a side of a polygon to form an exterior angle.
