Any polygon with 4 or more sides can always have a right angle.
Any shape with 4 or more sides is a polygon
either an obtuse, acute, or right angle
Any polygon can have just one right angle, from a right angled triangle upwards.
A right angle triangle
3 right angles
A polygon with 4 or more sides can have more than one right angle.
Any polygon can have a right angle. A right angled triangle is an example.
A polygon is pretty much any enclosed shape constructed of straight line segments connected end to end. The angles do not have to be right. In fact, they usually aren't. A right angle would NEVER be a polygon, as it is just one right angle. In Euclidean geometry a right angle must be accompanied by two acute angles to form a triangle--the polygon with the smallest number of sides.
Any polygon, if it is not regular, can have 1 right angle.
A right angle triangle
It can but need not.
It is a right angle triangle
A right trapezoid.

The interior angle and central angle are supplementary, that is they always add up to 180 degrees, while the exterior angle and the central angle will always be the same.
No, no! A RIGHT angle is 90 degrees.
There is only one regular polygon which contains right angles - this is a square. None of the other regular polygons from 3 sides and upwards has a right angle.
