Mathematical Induction

Mathematical induction is a fundamental proof technique used to establish that a statement holds for all natural numbers. It involves first proving a base case and then proving that if the statement holds for an arbitrary case, it must also hold for the next case.

Extended Principle of Mathematical Induction

Also known as strong induction, the extended principle of mathematical induction allows the assumption that the statement is true for all cases up to a certain number in order to prove it for the next case. This broader assumption can be particularly useful in more complex proofs where the inductive step relies on multiple previous instances.

Convex Polygon

A convex polygon is a polygon in which all interior angles are less than 180 degrees and every line segment drawn between any two points in the polygon lies entirely inside it. This property simplifies the analysis of its geometric properties, such as calculating the sum of its interior angles.

Interior Angle Sum

The interior angle sum of a polygon expresses a relationship between the number of sides and the measure of its internal angles. For convex polygons, this sum can be derived by dividing the polygon into non-overlapping triangles, leading to the formula (n-2) * 180° for an n-sided polygon.
