A reflex angle is over 180 degrees, but the sum of the angles in a quadrilateral, concave or convex, is 360. Therefore, since 180+180=360, you can't have any more degrees even without the amount over 180 that the reflex angle has.
This is an arrowhead quadrilateral.
A chevron.
Yes. One. The quadrilateral then looks a bit like a boomerang, according to my daughter. We had to establish this answer in her year 7 maths homework.
