The Peasant Wedding is one of Pieter Bruegel's most familiar paintings.The images of the chunky waiters carrying the very large tray of food supported by wooden poles have been used in many an advertising campaign. How to capture everyday life was the artist's preoccupation here.Bruegel would often dress in peasant clothing and mingle with the crowd at events such as weddings and parties.he images of the chunky waiters carrying the very large tray of food supported by wooden poles have been used in many an advertising campaign.

A tetrahedron is a triangular pyramid with 4 faces; each is a triangle. A regular tetrahedron has all edge lengths equal. There are formulas for the volume and surface area of a tetrahedron:
In chemistry, a trigonal pyramid is a molecular geometry with one atom at the apex and three atoms at the corners of a trigonal base.When all three atoms at the corners are identical, the molecule belongs to point group C3v.his would result in the geometry of a regular tetrahedron with each bond angle cosâ1(ââ) â 109.5Â°. However, the three hydrogen atoms are repelled by the electron lone pair in a way that the geometry is distorted to a trigonal pyramid (regular 3-sided pyramid) with bond angles of 107Â°.
