The ancient Romans invented shapes.
The 2 types of shapes are the geometric shapes and the organic shapes. Geometric shapes are ones that can be described using mathematical formulas. They also have specific math names. Geometric shapes: Circle, Square, Rectangle, Triangle, etc. Organic shapes are irregular and uneven.
There are 29 distinct pentominoes in three dimensions. 5 pairs of them are mirror images and can be rotated in 4-space to be considered the same. There is one 4D pentomino that cannot be built in 3D for a total of 24 4D pentominoes.
There are hundreds of shapes; some shapes are square, triangle, circle, rectangle, oval, octagon, hexagon, pentagon, cube, cylinder, and lots of combinations of shapes that form new shapes.
4D shapes are shapes in four dimensional space. Since we live in 3D space it is very difficult for most people to visualise 4D shapes.

8 - 4d = 12-4d = 4d = -1

In 4D space, an additional dimension is added to the three dimensions of traditional 3D space. This extra dimension allows for more complex shapes and movements that cannot be represented in 3D space. The concept of 4D space is used in mathematics and physics to explore higher-dimensional spaces beyond our everyday experience.
4d is time...any moving object is 4d
there is no 4d known to man
