If P(0, 1, 2), Q(4, -2, 1) and R(0, 0, 0) are three
points, then `anglePRQ` is

If P(0,1,2),Q(4,-2,1) and O(0,0,0) are three points, then /_POQ=

If P(0, 1, 2), Q(4, -2, 1) and O(0, 0, 0) are distinct points the manglePOQ = ______.

If P(0,1,2),\ Q(4,-2,1)a n d\ O(0,0,0) are three points then angle P O Q= a. pi/6 b. pi/4 c. pi/3 d. pi/2

If P(0,1,2),Q(4,-2,1) and O(0,0,0) are three points then POQ=(pi)/(6) b.(pi)/(4) c.(pi)/(3) d.(pi)/(2)

If P = (0, 1, 2), Q = (4, -2, 1), O = (0, 0, 0) then anglePOQ=

If P = (1,0), Q = (-10) and R = (2, 0) are three given points, then the focus of a given points S satisfy the relation SQ^(2)+SR^(2) = 2SP^(2) is a:

If P=(1,0), Q=(-1,0) and R=(2,0) are three given points, then the locus of S satisfying the relation S Q^(2)+S R^(2)=2 S P^(2) is

If P(1,0),Q(-1,0) and R(2,0) are three given points,then the locus of the point S satisfying the relation (SQ)^(2)+(SR)^(2)=2(SP)^(2)
