Discrete Geometry is like playing with blocks! When you have a bunch of blocks (points) and you want to look at how they fit together, you're doing discrete geometry. It's a type of math that helps us understand how points, lines, and shapes relate to each other.
Computational geometry is like a game where you're trying to fit different shapes together. But instead of just using your eyes and hands, you use a computer to help you! Computational geometry uses algorithms and programs to solve problems related to shapes and their relationships.
So, if you have a lot of blocks and you want to know how best to stack them up, you can use computational geometry to figure out which way to put them so that they don't fall over. Or, if you want to know the shortest distance between two points, you can use algorithms to find the answer quickly and accurately.
Overall, discrete and computational geometry are two types of math that help us understand how shapes relate to each other, and they're both really fun to explore and play with!
