Many a times, we prove a proposition directly from what is given in
the proposition But some times it is easier to prove an equivalent proposition rather
than proving the proposition itself This leads to, two ways of proving a proposition
directly or indirectly and the proofs obtained are called direct proof and indirect proof
and further each has three different ways of proving which is discussed below Direct Proof  It is the proof of a proposition in which we directly start the proof with
what is given in the proposition
