Finite geometry

Finite geometry is a type of math that studies shapes and points that are on a flat surface (like a piece of paper). Finite geometry has a limited number of points and shapes that it looks at and studies. Usually, 3 or more points are needed to study the area of a flat surface (like a triangle). These points and shapes have special rules that they need to follow and it's the job of mathematicians to figure out what those rules are. Finite geometry is an important part of mathematics and helps us to understand more about the ways shapes interact with each other on a flat surface.
