In a graph Sheet Plot each pair of points, join them by line segments (i) (2,5), (4,7) (ii) (-3, 5), (-1, 7) (iii) (-3, -4), (2,-4) (iv) (-3, -5), (2, -5) (v) (4,-2), (4,-3) (vi) (-2,4), (-2,3) (vii) (-2, 1), (-2,0) Now join the following pairs of points by straight line segments, in the same graph. (viii) (-3,5), (-3,4) (ix) (2,5), (2,-4) (x) (2,-4),(4,-2) (xi) (2,-4), (4,-3) (xii) (4,-2), (4,7) (xiii) (4,7), (-1, 7) (xiv) (-3,2), (2,2) Now you will get a surprise figure. What is it?
