  1. Measuring Angles In Digital Images Presented by Stephen Schneider

  2. Angles in Nature leaf branching angles

  3. Eratosthenes: The Size of the Earth Eratosthenes realized: Distance/Circumference = Angle / 360 (from Cairo) Circumference = 700 km × 360 / Angle = …

  4. Eratosthenes: The Size of the Earth (cont) Eratosthenes realized: Distance/Circumference = Angle / 360 Circumference = 700 km × 360 / 6.5° = 38769.2308 km Circumference = 700 km × 360 / 6.5° Circumference = 700 km × 360 / 6.5° = 38769.2308 km ≈ 40,000 km

  5. Human Family Tree Try to line up teeth (near and far) so they make a straight line —unlike this image Facial Slope

  6. Facial Recognition What other angles do you think might be diagnostic?
