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.

What is chevron in concave quadrilateral type?

It is also called an arrowhead. It is a kite with one of the vertices between equal sides "pushed in" so that it becomes a reflex angle.


Can a quadrilateral have an interior reflex angle?

Yes


Why must concave quadrilaterals be irregular?

A regular polygon has all its angles of equal measure, and its sides of equal length. In the case of a quadrilateral, that would mean a square. A concave quadrilateral must have at least one reflex angle and so cannot be a square. So it cannot be regular.


Can quadrilateral have more than one reflex angle?

No.


What is the largest angle in quadrilateral?

Any angle <360 degrees is possible, though it would be a concave quadrilateral if the angle were greater than 180 deg.


What quadrilateral has one reflex angle and 2 pairs of adjacent sides equal?

A quadrilateral with one reflex angle and 2 pairs of adjacent sides equal is called a kite. A kite is a type of quadrilateral with two distinct pairs of adjacent sides that are equal in length. Additionally, a kite has one reflex angle, which is an angle greater than 180 degrees.


Can a quadrilateral have a reflex angle?

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.


Can a quadrilateral polygon have an interior reflex angle?

Yes - a chevron or arrowhead.
