P + Q to Anisole overset(HI)(to)R + S Correct statement among the following is

Let P, Q, R and S be statement and suppose that P rarr Q rarr R rarr P . If ~S rarr R , then

Let P, Q, R and S be statement and suppose that P rarr Q rarr R rarr P . If ~S rarr R , then

If the inverse of implication p rarr q is defined as ~p rarr ~q , then the inverse of the proposition (p ^^ ~q) rarr r is not equivalent to : I : ~r rarr p vv q II : ~p vv ~q rarr ~r III : r rarr p ^^ ~q The true statements in the above are :

If the magnitude of vectors overset rarr P,overset rarr Q and oversert rarr R are 3,4 and 5 units respectively,and if overset rarr P + overset rarr Q = overset rarr R ,then what will be the angle between overset rarr P and overset rarr R ?

In Figure, P Q R is a triangle and S is any point in its interior, show that SQ+SR < PQ+PR. Given : S is any point in the interior of P Q R To Prove : S Q+S R < P Q+P R Construction: Produce Q S to meet P R in T
