Let's plot the points representing the coordinates (1,3),(0,5), (2,1),(3,3),(1,3),(2, 5) and (0,0) on the graph paper.

Let's plot the points A (4,0), B(0,6), C (2,5), D(7,1) E (?, 5) and F(?,5) on a graph sheet.

The point P is equidistant from the points (-1,4,2), (2,1,2) ,(3,2,2) and (0,5,6) , find the coordinates of the point P.

If PxxQ={(2,-1),(3,0),(2,1),(3,1),(2,0),(3,-1)} , find P and Q.

Find the coordinates of the point equidistant from the four points ( 2 ,1 , 2 ) ,( -1 , 1, 3) ,( 0 , 5 , 6) and (3 , 2 , 2) .

Let’s put the points (1,1),(2,2) and (3,3) on the graph paper and see whether they are collinear.

Show that the points (-2,3,5) ,(1,2,3) and (7,0,-1) are collinear

Show that the points P(-2,3,5) ,Q (1,2,3) and R (7,0,-1) are collinear

Show that the points (2,1) (0,0) (-1,2) and (1,3) are the vertices of a square.

Find the coordinates of the points of trisection of the line-segment joining the points ( 2 , 1 , - 3) and ( 5 , - 8 , 3) that is nearer to ( 2 , 1 , -3) .

If R={(1,-1),(2,0),(3,1),(5,3)} is a relation then R^(-1) is
