It can, but does not have to.
No. For a start, a circle has no angles. No regular polygon has a reflex angle.
A rhombus
A reflex angle
An arrowhead
The shape described is a kite, which is a quadrilateral with two pairs of equal adjacent sides and one reflex angle. A kite has an axis of symmetry along the line connecting the midpoints of the non-congruent sides. The reflex angle in a kite is typically greater than 180 degrees, creating a distinct shape that is not a regular quadrilateral.
parallelogram!
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
cheesse
They are congruent angles if they have the same shape and size.
Answer Reflex Angle
A rectangle is not an angle at all. It's a flat shape that looks like a box. A rectangle can never have a reflex angle inside it. But it always has four of them on the outside.
