Arches and domes use circular geometry to distribute weight evenly, allowing for strong, open structures.

The exact middle point. All measurements start here. Radius ( ): The distance from the center to any point on the edge. Diameter ( Circles

Circles aren't just math problems; they are fundamental to how the world works: Arches and domes use circular geometry to distribute

You see circles in the shape of orbits, pupils in eyes, tree rings, and water ripples. allowing for strong

): The total distance around the edge (the "perimeter" of the circle).

To understand a circle, you need to know its four defining parts:
