An arrow head
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, it is possible to draw a quadrilateral with a reflex angle and an obtuse angle. A reflex angle measures more than 180 degrees, while an obtuse angle measures between 90 and 180 degrees. To create a quadrilateral with these angles, you can draw a shape with one reflex angle (greater than 180 degrees) and one obtuse angle (between 90 and 180 degrees), along with two acute angles (less than 90 degrees).
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.
