Comparison of means
This GeoGebra activity shows four different means of two values a, b:
- AM = arithmetic,
- GM = geometric,
- QM = quadratic,
- HM =harmonic
geometrically.
The values are dynamically shown as segments on the diameter of a semicircle, and can be modified by moving point X.
Move point X to explore the means of a and b, and explore the inequality
.
