Think of a triangle. It has three sides, but it also has three vertices. Each one is like a tiny meeting point for two lines. Without vertices, squares would just be weird loops.
Here’s a fun fact: A circle has zero vertices. Why? It’s all curves, no corners. So your morning bagel? Zero vertices. Your pizza slice? Three. Mind blown yet?
When Lines Cross Paths
Now let’s get a little wild. Vertex isn’t just for shapes. In angles, the vertex is the pivot point. Picture two lines extending from the same dot. That dot is the vertex. It’s the boss of the angle.
I love this part: The vertex is always named with the middle letter. If you have angle ABC, the vertex is at B. So B is the VIP. Nobody invited A or C to that party.
