23.4. Triangulations of Convex Polygons

Try these first

1. 1.

   What is a triangulation?

   Hint

   Think about how you can split up shapes.

2. 2.

   How many sides does a triangle have?

   Hint

   Count the edges.

3. 3.

   What defines a triangulation?

   • Dividing into squares
   • Dividing into triangles
   • All sides equal

   Hint

   What shapes do we create in a triangulation?

4. 4.

   True or False: A triangle has multiple triangulations.

   • True
   • False

   Hint

   Consider the nature of a triangle.

5. 5.

   Given a polygon with 8 sides, derive the number of triangulations using the Catalan number formula.

   Hint

   Apply the nth Catalan number formula and track your calculations.

6. 6.

   Create a real-world scenario where triangulation is essential, and explain how you'd calculate the triangulation count.

   Hint

   Think about practical applications in navigation and mapping.
