AlBr3 - Aluminum Tribromide:

First draw the Lewis dot structure:
AlBr3 Lewis Structure
Electron geometry: trigonal planar. Hybridization: sp2

Then draw the 3D molecular structure using VSEPR rules:
  Click and drag the molecle to rotate it.

The molecular geometry of AlBr3 is trigonal planar with symmetric charge distribution around the central atom.
Therefore this molecule is nonpolar.
