While searching for a geometric proof for pi, I have found many interesting things.
The mathematics, a different approach.
The maths (advanced).
The triangles (blue/green). The power of a point.
The triangles (red/yellow). Every angle has two faces (with one exeption)
The angles and relationship. All angles derived from a single angle (theta).
Every angle has four related triangles.
The four angles used for comparison.>
The relationship between the angles (square roots).
The metallic means.
Red/Blue Triangles, Geometry Engine, Angle Machine, Geomatron.
All numbers (yes, even pi) can be expressed as an angle.
