Himanshu is right
first find out the hybridization...
use the formula
no of orbitals = 1/2 (v + m - c + a)
v= valence electrons in central atom
m = no of monovalent atoms connected to central atom
c = cation charge (if any)
a = anion charge (if any)

for eg.

methane
v = 4 (carbon has 4 valence electrons)
m = 4
c = a = 0

apply formula
no of orbitals = 1/2 (4+4) = 4
thus we have sp3
now use the table u might have in ur reference book

sp = 180 degree planar
sp2 = 120 degree planar
sp3 = 107.5 tetrahedral
etc etc

Please Rate Me if u found my info satisfying
