Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the mathematical transformation?Approximation of continuous geometric shapes using discrete polygons
2. What is the algorithmic foundation?Essential for computational geometry and computer graphics algorithms
3. Why do computers use polygons instead of curves?Computers work best with flat pieces because they can handle simple shapes quickly. Using polygons lets computers draw pictures, run simulations, and do engineering calculations faster.
4. How do we turn a shape into triangles?One common way is triangulation, where the shape is cut into triangles using methods like ear clipping or Delaunay triangulation. This makes the shape into many small, non-overlapping triangles.

Discretization: The process of converting a continuous domain into a discrete one, often using polygons.
Mesh: A collection of vertices, edges, and faces (polygons) that define a shape or surface.
Finite Element Analysis (FEA): A method for predicting how a product reacts to real-world forces, vibration, heat, and other physical effects using polygonal approximations.
