Bézier triangle

A bézier triangle is like a special kind of shape that is made up of points and lines. You can use this shape to make cool 3D objects and images on the computer.

It's like when you draw a triangle with a pencil, but you can also imagine that there is a "rubber band" stretching from each corner of the triangle to different points inside the triangle. If you move these rubber bands around, you can change the shape of the triangle.

Scientists invented something called the "bézier" formula to help them calculate exactly where each rubber band should go to make the triangle look the way they want.

And when you use this formula to make a triangle with a lot of points and lines, it can look really cool and make amazing shapes that you can even move around and see from different angles.
