No, a quadrilateral cannot have more than one reflex angle. A reflex angle is an angle that is greater than 180 degrees but less than 360 degrees. If a quadrilateral had more than one reflex angle, the sum of its angles would exceed 360 degrees, violating the fundamental property that the sum of the interior angles of a quadrilateral is always 360 degrees. Thus, a quadrilateral can have at most one reflex angle.
No, it has four.
A quadrilateral, by definition, is a four-sided polygon with four angles. If a shape has only three angles, it is classified as a triangle, not a quadrilateral. Therefore, a quadrilateral cannot have just three angles; it must have four angles that sum up to 360 degrees.

A quadrilateral can have three acute angles if it is an irregular shape, specifically a type of concave quadrilateral. In such a case, the fourth angle can be obtuse or even reflex, allowing the sum of the angles to equal 360 degrees while still accommodating three acute angles. However, it's important to note that a convex quadrilateral cannot have three acute angles, as the fourth angle would then have to be obtuse to satisfy the angle sum property.

No. All quadrilaterals can be made from joining two triangles, hence they all have interior angles that sum to 360 degrees. Reflex angles are greater than 180 degrees so two reflex angles would be too big!

Yes, it looks like an arrowhead and is called a concave quadrilateral.
There can be at most 3 obtuse angles in a quadrilateral.
A bit like a chevron or an arrowhead.
No, it has four.
No a quadrilateral can't have 3 obtuse angles and 1 right angle because if a polygon did have 3 obtuse angles and 1 right angle then it would not even be a quadrilateral.
A kite does not have a reflex angle because it is a 4 sided quadrilateral that has 4 interior angles that add up to 360 degrees and 4 exterior angles that add up to 360 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.
