Yes - a chevron or arrowhead.
Yes
A polygon in which the sum of all the interior angles is 360 degrees is a quadrilateral.
The sum of the interior angles of a quadrilateral are 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.
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.
Reflex angle
No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more.
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. For a start, a circle has no angles. No regular polygon has a reflex angle.
The size of an angle in a polygon depends on the number of sides the polygon has. The sum of the interior angles of a polygon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. To find the measure of each interior angle in a regular polygon (where all angles are equal), divide the total sum by the number of sides. For example, a triangle has a total interior angle sum of ( 180^\circ ), while a quadrilateral has ( 360^\circ ).
