Both "oval" and "oblong" are adjectives often used to describe shapes or outlines. While "oval" is defined as "having the general form, shape, or outline of an egg," "oblong" is defined as "elongated, usually from the square or circular form."
Know MoreAn oval can be classified as an oblong or elongated circle. An object with an oval shape can be described as oblong, but not all oblong objects can be described as oval. Other words used to describe oval shapes are elliptical and ellipsoidal.
Oblong objects can be elongated circles, such as ovals, but can also be elongated squares. A second definition of oblong is "in the form of a rectangle one of whose dimensions is greater than the other."

Full Answer >A cube is a six-faced, three-dimensional figure composed of square-shaped faces of the same size that meet at 90-degree angles, whereas a cuboid is a box-shaped object made of six faces that all meet at 90-degree angles. A cuboid shape can also be a cube if all sides are the same length, but not all cuboids are cubes. Cubes and cuboids contain eight vertices and 12 edges.
Full Answer >"Concave" is an adjective describing a surface that curves inward, like the inner surface of a sphere. Its antonym, "convex," describes a surface that curves outward, like the exterior of a sphere. In geometry, concave and convex refer to polygons. A concave polygon has at least one angle greater than 180 degrees. A convex polygon is made of angles each less than or equal to 180 degrees.
Full Answer >The difference between a kite and a rhombus is that a kite does not always have four equal sides or two pairs of parallel sides like a rhombus. A kite is a four-sided shape that has two sets of adjacent sides that have equal lengths. All rhombuses and squares are also kites.
