Oh, dude, let me break it down for you. So, we've got this quadrilateral ABCD with all these angles, right? And we need to find angle AEB, where E is the intersection point of AC and BD. Like, just do a little math magic with those angles, and you'll see that angle AEB is 80 degrees. Easy peasy, lemon squeezy!

none of these answers are correct
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.
A convex polygon is one with no angle greater than 180 degrees. A non-convex polygon is one that is not without such an angle.
a square or a rectangle
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
concave

The sum of the exterior angles of a polygon equals 360.Quadrilateral has 4 exterior angles.360/4=90 for a regular quadrilateral.
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.
An angle that is > 180
