Three Sides?

How many things with three sides you can think of other than 3-D?

Well, our tongue can distinguish tastes in Sweet, Sour and Salt...our life cycle has three stages - as a Child, as a Grown-up and as an Old...then personality shades of Black, White and Gray....Hindu belief in God's trilogy - Brahma the Creator, Vishnu the Preserver, and Shiva the Destroyer.....In Christianity, doctrine of Trinity - the Father, the Son and the Holy Spirit. Ofcourse, three branches of a government - Executive, Legislative and judicial.

And finally a classic - The Good, The Bad and The Ugly!
