if they have given literally, first draw the diagrams. then
use congruence rules to solve it. if
needed we can draw extra lines. as area of llgm and triangle have theorem, most
of the questions will be of theorems. so don't forget to apply theorems.
always try to make figure into triangles and try to prove
any two triangles equal.
don't forget to practice sums again and again, so that you
need not break your head during exam, also you will have less time.
do the sums from guides. i would recommend you R.D.SHARMA guide.
