A polygon that does not have a right angle is a triangle, specifically an obtuse triangle, which has one angle greater than 90 degrees. Additionally, any polygon with angles that are all acute (less than 90 degrees), such as an equilateral triangle or a regular pentagon, also does not contain a right angle. Therefore, there are numerous polygons, including various types of triangles and other shapes, that can be defined without a right angle.
Any polygon can have a right angle. A right angled triangle is an example.
