What is vertex?

A vertex is like a corner where two sides of something meet, just like the corners on a box or a table.

Imagine you're playing with building blocks. Each block has corners, and those are your vertices. They’re the points where the edges come together. If you look at a cube, which is like a 3D square, it has eight of these special corner points, all vertices!

Think about a shoebox sitting on your table. Every time you see a corner sticking out, that's a vertex. A box has six faces (like the sides), twelve edges (the lines where two faces meet), and eight vertices, just like the corners of a cube.

Now imagine drawing shapes on paper. When you draw a triangle, each point at the end of a line is a vertex. That triangle has three vertices, and if you connect them, they make the whole shape!

So whether it's a box, a triangle, or any other shape, a vertex is just a corner where edges meet! A vertex is like a corner where two sides of something meet, just like the corners on a box or a table.
