All the angles below are reflex angles:

Notice that I have used the same angles as on the Obtuse Angles page. The obtuse angle is the other side of the lines. When naming the angles make sure that you know which angle is being asked for.

If you look at both pages and add the reflex and the obtuse angle for each shape you will always come to 360°
