The Ungerecht Family Tree

• Angles and Vectors
• Polygons
• Triangles
• Circles, Chords, etc
• Graphing curves, circles, etc.

The sum of angles in a polygon = 180 (n - 2), where n = number of sides. This can also be written as: 180 + 180 (n-3). (Basically you add in another triangle when adding a side to polygon)
