Yes
Yes - a chevron or arrowhead.
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.
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.
The only quadrilaterals with a reflex angle are arrowheads (or chevrons).
Possibly in the form of an arrowhead providing that its 4 interior angles add up to 360 degrees
a kite or a dart * * * * * Not a kite: all its angles are less than 180 degrees.
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
No.
An interior angle is the inside angle of a shape e.g quadrilateral, square
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.
A heptagon. It can have a reflex interior angle, a triangle cannot.
The sum of the interior angles of a quadrilateral is 360 degrees.
