This GeoGebra activity shows four different means of two values a, b.
(AM = arithmetic, GM = geometric, QM = quadratic and HM =harmonic) geometrically .
The values are dynamically shown as segments on a semicircle's diameter, and can be modified by moving point C.
Move point C to explore how the means associated to a, b vary accordingly, and explore the inequality:
