A two dimensional shape is a flat shape. Its extent is given by two measures of distances. These are often called length and breadth, but unfortunately, other words are also used: breadth, height (WxH for a poster, for example).
A three dimensional shape is a solid shape whose extent requires three measures of distances. These are usually the length, breadth and height (but width can replace one of them).
It is, of course, possible to specify the shape using fewer or more measures. The size of a circle or sphere are wholly specified using only one measure - the radius or diameter. On the other hand a quadrilateral (2-d shape) needs 5. Given only the lengths of the 4 sides, it is always possible to flex a quadrilateral to make a different shape.

Drawing and painting are two-dimensional, sculpture is three-dimensional.
Area is the measure of a two-dimensional space enclosed by a shape, and surface area is the sum of all the areas of the faces of a three-dimensional solid.
An oval is two-dimensional. An ovoid is a three-dimensional shape based on an oval - like an egg,
An egg-shaped, three-dimensional shape is an ovoid.
Almost everything is different!A polygon is a closed shape in 2 dimensional space, bounded by straight lines. Three dimension is a description of normal space.
