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 quadrilateral has two pairs of equal lines one pair of equal angles and one reflex angle?
This is an arrowhead quadrilateral.
What shape has 4 sides but only 1 right angle?
It could be a kite, an arrowhead or an irregular quadrilateral with a right angle - which has no specific name.
What do you call a angle larger than 180 degrees?
Reflex angle
How much is an reflex angle?
A reflex angle is between 180 degrees to 360 degrees
Is 180 degrees a reflex angle?
No, 180 degrees is a straight angle. A reflex angle is one whose value is between 180 and 360 degrees.
Does a quadrilateral have a convex or a concave angle?
concave
A arrowhead is a concave polygon as it has a what angle?
Reflex angle
Which quadrilateral does not have a reflex angle?
The only quadrilaterals with a reflex angle are arrowheads (or chevrons).
What is concave hexagon?
It is a hexagon with a reflex angle.
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 is a irregular five sided shape with one reflex angle?
A concave pentagon.
Can a quadrilateral polygon have an interior reflex angle?
Yes - a chevron or arrowhead.
Quadrilateral with 3 acute angles and 1 reflex angle?
