Oblong means 'a non-square rectangle'.
In geometry, a rectangle is any quadrilateral with four right angles. The term oblong is occasionally used to refer to a non-square rectangle.
A rectangle is equiangular, meaning all of its corner angles are equal. The shape is also isogonal meaning all corners lie within the same symmetry orbit. Finally, it has two lines of reflectional symmetry and rotational symmetry through 180 degrees.
Put simply, an oblong shape is four lines connected at four corners. The lines are in two pairs with one pair being longer than the other.
All angles of an oblong shape are congruent meaning they are the same.
The centre of the shape is equidistant from its vertices (in other words its corners), so it has a circumcircle. This is a circle which passes through all the vertices of the polygon.
Also, an oblong shape's axes of symmetry bisect opposite sides.
A rectangle is similar to a rhombus but not the same. While a rhombus must also have angles that are congruous, its axes of symmetry bisect opposite angles. Plus its centre is equidistant from its sides, hence it has an incircle.
While all of this sounds complicated, oblong shapes are one of the first geometric forms taught to children. From the age of five when first at school they are taught to identify squares, circles triangles and rectangles through visual clues. Only in their later years do they learn the properties of these shapes that make them what they are.
