Intermediate Geometry explores the properties and relationships of shapes, sizes, and theorems in two and three dimensions.
A polygon is a closed shape with straight sides. The number of sides determines the polygon's name (pentagon - 5, hexagon - 6, etc.).
The sum of the interior angles of a polygon is: \[ (n - 2) \times 180^\circ \] where \(n\) is the number of sides.
Polygons are everywhere: stop signs (octagons), honeycombs (hexagons), and tiled floors often use regular polygons for symmetry and design.
The more sides a regular polygon has, the closer it resembles a circle!
A pentagon has five sides and its interior angles sum to \(540^\circ\).
A soccer ball's surface is made up of hexagons and pentagons.
Polygons are multi-sided shapes with angle and side properties used in art, architecture, and nature.
