Basic and Rich Geometry Concepts Part 6, Proof of triangle area from medians

thumb_basic and rich geometry concepts part 6 area of triangle and medians proofs top

Medians are one of the most important set of elements related to a triangle. The symmetry associated with the medians give rise to a rich set of concepts and relations. In addition to a number of important area related concepts, we will discuss here how to find the area of a triangle from the given length of its medians...

Principle of disproportion saved us millions this time

thumb_principle of disproportion

All things in nature are in proportions that we accept and have become used to. Mimicking nature we build our things that also follow rough proportional relationships that we are not always explicitly aware. But when such a proportional relationship is violated outright we might feel something is wrong, if we have the principle of disproportion imbued in us.
